About this document Intended audience This document is intended to be used by technical professionals who manage multiple HP BladeSystem enclosures and use HP Virtual Connect Manager to control network connectivity. HP assumes that you have installed Virtual Connect, are familiar with the embedded Virtual Connect Manager web console, and have read the HP Virtual Connect for c-Class BladeSystem User Guide and understand its concepts.
1 Introduction HP Virtual Connect Enterprise Manager (VCEM) centralizes network connectivity and workload mobility for HP BladeSystem servers that use Virtual Connect to access local area networks (LANs) and Storage Area Networks (SANs), helping organizations to increase productivity, respond faster to workload and infrastructure changes, and reduce operating costs.
• Increase productivity and server-to-administrator ratios. • Release LAN and SAN administrators from routine server-centric tasks. • VCEM scales across small and large data centers. What's new VCEM 6.0 is an update to VCEM 1.20, 1.3x, and 1.40 that adds new features and support for the latest Virtual Connect hardware and firmware which includes: • Support for the HP Virtual Connect 8Gb 20-Port Fibre Channel module for BladeSystem c-Class. • Operations with Virtual Connect firmware 2.
NIC or HBA addresses. Even if a server is replaced, the MAC and WWN assignments for the enclosure will remain the same, and changes are invisible to the network. Virtual Connect provides the following benefits: • Significantly reduce cabling and server connection complexity. • Maintain constant end-to-end connections to preferred networks and fabrics. • Separate server administration from LAN and SAN administration.
HP Virtual Connect Enterprise Manager VCEM is HP’s primary application for managing Virtual Connect environments. It provides centralized group-based management for up to 250 Virtual Connect domains with the VCEM 6.0 release, administers a total of 256K LAN and SAN addresses from a central pool, and enables server profile movement across the datacenter. Typical Environment Multiple rack or distributed BladeSystem environments with more than one rack of enclosures and with plans to expand.
Figure 1-2 Virtual Connect Enterprise Manager operations VCEM centralizes Virtual Connect infrastructure management and increases productivity. Setup and configuration summary To set up and configure VCEM into an existing HP BladeSystem environment running Virtual Connect: 1. 2. Verify that existing Virtual Connect module firmware and HP Onboard Administrator firmware meets the minimum requirements.
2 Installing and configuring VCEM This chapter describes how to install and configure VCEM. IMPORTANT: This guide assumes that you have previously installed Virtual Connect using the integrated Virtual Connect Manager, have read the HP Virtual Connect for c-Class BladeSystem User Guide, and understand its concepts. Preparing for a VCEM installation If you have VCEM 1.10 or earlier, you must first upgrade to VCEM 1.20 using the HP Insight Software DVDs. VCEM 6.0 can directly update installations of VCEM 1.
3. (Optional) If you are installing VCEM as part of the HP Insight Software suite, after performing an HP SIM discovery, access the HP Managed System Software Wizard and complete the steps in the wizard. For more information about the wizard, see the HP Insight Software Installation and Configuration Guide. NOTE: VCEM 6.0 does not support VC firmware 1.3x or 1.2x. If you have these versions of VC firmware, you must upgrade to at least 2.0x.

Creating a VC Domain Group You can create a VC Domain Group by selecting the VC Domains that you want to incorporate into a new VC Domain Group. IMPORTANT: This VCEM operation does not provide a reference to the VC Domain from HP SIM. To access this reference, you must correlate the HP SIM and Virtual Connect logs. For more information, see Correlating VCEM operations in HP SIM and Virtual Connect logs. VCEM supports multienclosure VC Domains.
4. Enter the VC Domain Group name in the VC Domain Group Name field. Valid VC Domain Group names are alphanumeric, hyphens (-), underscore (_), and cannot exceed 64 characters. 5. From the Configuration based on VC Domain list, select the VC Domain configuration upon which the new VC Domain Group is to be based. The Configuration VC Domain list contains only configured VC Domains. 6.
• If HP Virtual Connect 8Gb 24-port FC modules and HP Virtual Connect 4Gb FC modules share the same IO bay slice. (For example, a HP Virtual Connect 4Gb FC module in IO Bay 3 and a HP Virtual Connect 8Gb 24-port FC module in IO Bay 4). • In a multienclosure VC Domain, if there are mixed HP Virtual Connect 4Gb FC modules and HP Virtual Connect 8Gb 24-port FC modules in the same IO bay from different enclosures.
deleting the VC Domain Group or removing the VC Domain from a VC Domain Group. HP recommends that you provide MAC, WWN, and serial number ranges that are: • Not in use by VCEM. • Not in use by any other VC Domain in your network You can click Remove from VCD Group only if the current selection contains VC Domains that belong to VC Domain Groups. After removing a VC Domain from a VC Domain Group, you can edit or change the existing profiles from the Virtual Connect Manager user interface.
The following figure illustrates a valid configuration of Ethernet and Fibre Channel Virtual Connect modules in a VC Domain with multiple enclosures. The black lines linking the Ethernet modules illustrate the stacking links. VCEM supports VC Domain Groups containing VC Domains with multiple enclosures, and enables the VC Domains to contain different numbers of enclosures, as long as each VC Domain contains the minimum number of enclosures. The Ethernet uplinks define the minimum number of enclosures.
Figure 3-12 VC Domain Group with VC Domains that have different numbers of enclosures A multienclosure domain can only be configured as follows: • The enclosure must be a c7000 enclosure. • Primary and secondary Virtual Connect Ethernet modules must be either the HP 1/10Gb-F Virtual Connect Ethernet Module or the HP Virtual Connect Flex-10 10Gb Ethernet Module running VC firmware 2.1x or later. • FC modules in every enclosure must match the model and disposition.
automatically to all other VC Domains that belong to the same VC Domain Group. VCEM accomplishes this task by temporarily enabling domain, network, and storage changes through the local Virtual Connect Manager for the selected domain.
VC Domain Group configuration replicated to other VC Domains during VC Domain Maintenance IMPORTANT: The VC Domain, network, and storage configuration changes performed during VC Domain Maintenance are automatically replicated to all other VC Domains that belong to the same VC Domain Group when the VC Domain that maintenance operation is confirmed or discarded.

IMPORTANT: When a VC Domain is put in VC Domain Maintenance, operations such as backup and restore Virtual Connect configurations are allowed. Restoring Virtual Connect configurations require additional care. If an old configuration is restored, verify that the configuration of this specific VC Domain remain compatible with VC Domain Group, otherwise the VC Domain will be incompatible with VCEM.
IMPORTANT: The domain configuration backup file created during VC Domain Maintenance and is valid for restoration while the VC Domain is in VC Domain Group. The domain configuration file is not valid after the VC Domain is removed from VC Domain Group.
IMPORTANT: For more information on the domain, network, and storage configurations that VCEM can replicate during completion of VC Domain Maintenance, or discard in case of a failure or cancellation of the VC Domain Maintenance operation, see VC Domain Group configuration replicated to other VC Domains during VC Domain Maintenance. To cancel a VC Domain Maintenance from the VC Domain page: 1. 2. 3. 4. Select the VC Domain with status under maintenance. Click VC Domain Maintenance.
4 Managing VC Domain Groups VC Domain Groups This section describes the management of Virtual Connect (VC) Domain Groups using VCEM. A VC Domain consists of an HP BladeSystem enclosure, a set of associated Virtual Connect Ethernet and Fibre Channel interconnect modules, and server blades that are managed together by a single instance of Virtual Connect Manager. The VC Domain contains specified networks, server profiles, and user accounts that simplify the setup and administration of server connections.
Status Icon Under maintenance Description VC Domain is unlocked for domain, network, and storage changes through the Virtual Connect Manager. After completing the domain network and storage changes, you must confirm the new VC Domain configuration in VCEM. VCEM operations related to this VC domain or to VC Domain Group, such as create profile, move profile, profile failover, and so on, are blocked while the VC Domain is under maintenance.
3. 4. Enter the username and password for each VC Domain. Ensure you provide VC Domain credentials will full privileges. VC Domains appear as: • Unconfigured domains, which appear in the System Name column with the unassigned name, VCD_name • Configured domains, which appear in the System Name column with their previously assigned name. Enter the username and password for the Onboard Administrator of each unconfigured VC Domain.
1. 2. 3. 4. 5. 6. 7. Select the VC Domain Group on which you want to perform maintenance. Click VC Domain Maintenance. Select the target VC Domain within the selected VC Domain Group which will be enabled for maintenance, and click Next. The VC Domain Maintenance page appears. To unlock Virtual Connect Manager for domain, network, and storage changes, click Make changes via VC Manager. Virtual Connect Manager web interface appears in a separate browser window.
completed, look at the report generated by the related job in the VCEM event. To access this report from the HP SIM left navigation panel, select Events→Shared→VCEM Events. IMPORTANT: This VCEM operation does not provide a reference to the VC Domain from HP SIM. To access this reference, you must correlate the HP SIM and Virtual Connect logs. For more information, see Correlating VCEM operations in HP SIM and Virtual Connect logs. VCEM detects the presence of logical server managers or upper level managers.
4. Perform the following actions for each VC Domain that uses HP-predefined or user-defined ranges within the VC Domain Group that you want to remove. Factory-default MAC and WWN ranges are released back to Virtual Connect Manager as Factory-default. If factory-default MAC or WWN addresses or serial numbers are not being used, address ranges must be specified for each removed VC Domain. These address ranges must be unique and distinct to prevent assignment of duplicate addresses.
3. For each VC Domain released from the VC Domain Group, insert or remove VC modules in the corresponding enclosure, and perform the necessary domain, network, and storage configuration changes in the VC Manager user interface. Before VC module removal, remove the VC module uplink ports from all existing Network or Shared Uplink settings from VC Domain configuration.
5 Managing server profiles Profiles This section describes how to create and manage profiles for use with VCEM. A Virtual Connect server profile is a logical grouping of attributes related to server connectivity that can be assigned to a server bay. A server profile can be assigned to any server bay within the VC Domain Group. VCEM requires the server to power down for any profile operations such as create, delete, unassign, copy, move, and edit. For more information on this procedure, see "Bays.
A server profile defines connections for a blade server. Server profiles can include the following information: • Profile name • Logical serial number and logical UUID • Ethernet network connections and PXE settings • MAC addresses • Fibre Channel fabric connections • WWN addresses • Server boot configuration • BIOS settings Newer VC Domain versions provide a broader set of configuration in the server profile.
power off the server blade to perform server profile operations with VC firmware 2.0x or 2.1x. However, in VC firmware 2.3x, you can perform these operations with the server blade powered on. Creating a profile NOTE: Depending on the VC Domain version, the create profile page displays a different set of configurations. To verify the available features for each VC Domain version, see the feature set table earlier in this section. NOTE: In a VC Domain Group with VC firmware 2.
Target boot LUN values must be compliant with proper ranges. ▲ VC Domains—You can provide the target boot LUN in either of the possible formats: • When using LUN values from 0–255, you can specify the LUN and either decimal or in 16-digit hexadecimal number format. • When using LUN values greater than 255, you must specify the LUN in 16-digit hexadecimal number format.

From this list, you can perform the following tasks: • Review a summary of jobs • Select and review details of jobs • Select and delete jobs Figure 9-1 Jobs list The following table lists and describes the job item columns in the Jobs list.
VCEM limits the number of jobs that it displays to 65,000. If the limit is reached, then only the most recent 65,000 jobs are viewable. To keep the list smaller, you can select the jobs to be deleted, and then click Delete. Reviewing job details To review the details of a particular job, click the hyperlink of the appropriate job name. The Job Details window appears. Deleting jobs To delete a particular job or multiple jobs, click Delete. Only pending, failed, or completed jobs can be deleted.
10 Upgrading Virtual Connect firmware after VCEM is managing VC Domains The process for upgrading Virtual Connect (VC) firmware requires extra steps when VCEM is managing the VC Domain. VCEM gains exclusive access to managed domains. However, using the VC Domain Maintenance capability, the Virtual Connect Manager can be used to upgrade VC firmware while the VC Domain is being managed by VCEM.
11 Removing an external manager account For VCEM to manage VC Domains (using the Virtual Connect Manager, the embedded software in a Virtual Connect Ethernet module) VCEM uses programmatic interfaces with each Virtual Connect Manager. VCEM automatically creates an external manager account in each Virtual Connect Manager for subsequent authentication. NOTE: VCEM uses a Secure Sockets Layer (SSL) connection provided by HP SIM.
12 Command Line Interface usage in VCEM VCEM provides support for a command line interface (CLI) to perform several failover-related functions. These same functions are also available in the VCEM GUI. Perform VC profile failover on specified VC Domain bay server This CLI command initiates a VC profile failover operation.
>vcem –list –details –job JobNumber If the CLI List Job Details command is successful, the exit code from the CLI is zero, and the following example output appears (through stdout) on the screen. >vcem –list –details –job 1 Listing details for specified VCEM Job...
CLI exit and error codes The CLI returns a numeric value that either indicates success or a particular error or failure. The CLI also displays an associated error message (through stdout). A zero numerical returned value indicates success. Some returned value greater than zero indicates an error or failure. The following list shows all possible exit and error codes and messages that might be returned by the VCEM CLI.
13 Troubleshooting VCEM Troubleshooting IMPORTANT: VCEM 6.0 supports the Microsoft Internet Explorer 8 (IE8) browser, but the underlying Virtual Connect Manager does not currently provide the same level of support. Using IE8 to perform VCEM Domain Maintenance tasks that access Virtual Connect Manager might result in failed or incomplete operations. HP recommends Microsoft Internet Explorer 7 (IE7) or Firefox 3.0 or 3.5 as the preferred browsers for use with VCEM.
The HP Virtual Connect has lost its login credentials for the HP Onboard administrator (OA). The OA may have been replaced or reset to factory defaults. To ensure proper operation, these credentials must be reestablished. When Onboard Administrator credentials are provided, an error message appears stating that the credentials are not valid. This situation can occur when: • Onboard Administrator is replaced or reset to factory default settings.
Cannot access VC Domain from Virtual Connect Manager after a data migration has been performed If, after performing data migration, you are running Virtual Connect Manager and try to access a VCEM-managed VC Domain, the following error message appears: VC Domain locked by Virtual Connect Enterprise Manager . To resolve this issue: 1. 2. 3. Go to the CMS and invoke the MS-DOS command box. Change directory into the \.
VC Domain displays Configuration Mismatch status If the VCEM data does not match the data from the VC Domain, then the Configuration Mismatch icon appears. This might happen when either the user suspends the external manager lock and then modifies the VC Domain, or adds or removes VC Modules from rear-enclosure interconnect bays. To correct this issue, see Resynchronizing a VC Domain with Configuration Mismatch.
If VC Domain firmware is 2.0x or later, perform the following: • To remove the account and release the VC Domain from VCEM control, from the Virtual Connect Manager command prompt, enter: remove external-manager Username=xyz mactype= MacStart=<> MacEnd=<> wwnType= WwnStart=<> WwnEnd=<> serverIdType= serverIdStart=<> serverIdEnd=<> NOTE: “-quiet” is an option to suppress user confirmation prompts.

To complete VC Domain Maintenance, click VC Domain Maintenance, or to revert back to the original VC Domain configuration, click Cancel. b.
Error on database operation occurs Errors might occur during database operations if: • VCEM tables are missing; that is, Database Administrator deleted some VCEM tables. • HP SIM database is not running. To resolve this issue: 1. 2. 3. If VCEM tables are missing, then you must restore the VCEM database backup. For more information, see Backing up and restoring VCEM. Check the HP SIM database server status: • If the database server is remote, then log in to the database server.
Creating a server profile or adding a VC Domain to a VC Domain Group fails Attempting to create a profile or adding a VC Domain to a VC Domain Group might fail if any of the following occur: • VCEM does not have enough free MAC or WWN addresses. • Some MAC or WWN addresses are already being used by another server profile. • The MAC or WWN addresses in use by the VC Domain are not defined as custom ranges in VCEM. To resolve this issue: 1. 2. 3. 4. Verify VCEM has enough free MAC and WWN addresses.
Figure 13-1 Backing up and restoring VCEM The Domain Network and SAN Configuration and assigned Server Profiles can be recovered from the Virtual Connect modules. The VC Domain Group definitions, MAC and WWN custom ranges, and MAC and WWN address exclusions are stored only on the Management Server. For more information on performing backups and restoring VCEM, see “Backing up and restoring HP Systems Insight Manager 5.
1. To remove the account and release the VC Domain from VCEM control, from the Virtual Connect Manager command prompt, enter remove external-manager Username=xyz mactype= MacStart=<> MacEnd=<> wwnType= WwnStart=<> WwnEnd=<> serverIdType= serverIdStart=<> serverIdEnd=<> NOTE: “-quiet” is an option to suppress user confirmation prompts. This option is useful for scripting operations.
4. 5. 6. 7. 8. 9. Replace the VC modules from the enclosure reader interconnect bays. Verify that the network and SAN connections that are wired to the new VC modules are the same as the old connections. If the primary VC Ethernet module was replaced, then you must configure the VC Domain again through virtual Connect. For more information about configuring the VC Domain, see the HP virtual connect for c-Class BladeSystem User Guide.
Error during Edit server profile [Profile Name]. Details: This action could not be performed because the server is powered on. Power down the server associated with the Server Bay and retry the operation. VCEM server profile editor does not prevent profile edit operations in case the target server is powered off. However, the VCEM server profile edit job might fail depending on what profile changes each VC Domain firmware version allows in case the target server is powered on.
As a result, VCEM might display false job results such as, "Completed with success," even though the server profile changes have not taken effect.
After a server profile failover, some connections defined in the server profile are not functional VCEM cannot identify if all Fibre Channel and Ethernet connections configured in a server profile can be physically mapped to the physical ports of a server blade, due to that it is possible to have Ethernet or Fibre Channel connections in the server profile that cannot be configured in the server blade where it is assigned, causing those servers to not function.
Create VC Domain Group or Add VC Domain to VC Domain Group operations fail and the message "An invalid boot LUN was entered. Check the storage arrays for the proper LUN number" appears VCEM requires the boot target LUN configuration and server profiles to be either a three-digit decimal between 0–255, or a 16-digit hexadecimal value between 0 and FFFFFFFFFFFFFFFF.
5. 6. 7. 8. Click the VC Domains tab, for each VC Domain with "Configuration Mismatch" status, click VC Domain Maintenance. To confirm the resynchronization of the selected VC Domain with the VC Domain Group configuration, click OK. Repeat steps 1 and 2 for the VC Domain where the changes were made. In the Virtual Connect Manager user interface, create the Ethernet networks (VLANs tagged) in the desired shared uplink set.

hardware status The operating state of SNMP-based systems. A hardware status is determined by polling SNMP information from the system. Status is defined as: • Critical. can no longer communicate with the system. The system was previously discovered, but cannot be pinged. The system might be down, powered off, or no longer accessible on the network because of network problems. • Major. A problem exists. • Minor. The system is functioning but with errors. • Normal. • Unknown.
Simple Network Management Protocol (SNMP) One of the management protocols supported by . Traditional management protocol used extensively by networking systems and most servers. MIB-2 is the standard information available consistently across all vendors. Smart Link A feature that, when enabled, configures a Virtual Connect network so that if all external uplinks lose link to external switches, Virtual Connect will drop the Ethernet link on all local server blade Ethernet ports connected to that network.
