2 Major Changes, New Features, and Requirements of Instant Capacity Version 10.x This chapter covers the following topics: • “Program Requirements” (page 19) • “Summary of New Features and Changes” (page 20) • “Known Problems” (page 27) • “Software Requirements” (page 32) • “Usage Rights Requirement” (page 35) • “GiCAP Requirements” (page 36) The following sections provide only a summary of the Instant Capacity Version 10.x major changes and features.
Summary of New Features and Changes This section summarizes the new features and changes of the Instant Capacity product. Changes in Version 10.01 from Version 10.00 (HP-UX) • • • Support for Temporary Instant Capacity (TiCap) on HP Integrity Superdome 2 Implementation of icapstatus command on HP Integrity Superdome 2. Added capability for warning period and out of compliance notifications on HP Integrity Superdome 2. Changes in Version 10.00 from Version 9.
Negative "cores without usage rights" fixed If simultaneous activations were requested on multiple partitions of a GiCAP group member that was authorized to use temporary capacity, then the update by the Group Manager might have resulted in a very large value for "cores without usage rights" on the group member, such that the value exceeded the field size and displayed as a negative number. Changes in Version 9.0 from Version 8.03.
Changes to the verbose status option of icapmanage With the V9 release, the verbose status command (icapmanage -s -v) attempts to contact every host of each group member to check that two-way communication can be established between the issuing group manager (either active or standby) and each such host. The icapmanage -s command without -v attempts to contact multiple hosts of a group member only if that is necessary to find a host that responds.
Internal Representation of the Group Manager In previous releases, the internal representation of the Group Manager was maintained as an IP address. It is now maintained by its host name. This enables the use of a GiCAP Group Manager using DHCP for dynamic IP addresses. New GiCAP Configuration File for Group Members In versions 9.0 and later, the file /etc/opt/iCAP/GiCAP.configFile is created on every host of a GiCAP group member.
The vparmodify and vparcreate commands are now bound by the containing nPar's intended active core count. Also note that in an integrated virtual partition environment, a boot time compliance check is performed whenever a virtual partition is booted.
Changes in the Application of RTU Codewords A negative TiCAP balance is no longer cleared when applying an RTU codeword. Also, improvements were made to the application of RTU codewords on GiCAP group members. With this release, the amount of core usage rights on a member cannot be more than the sum of the “number of cores without usage rights” and “borrowed core usage rights.
Changes in Asset Reporting Asset reporting is disabled by default on new installations of Instant Capacity. Asset reporting will remain at the previous setting for reinstalls and upgrades. Asset reporting can be enabled with the command icapnotify -a on. GiCAP member asset reports sent to the HP portal will reflect the correct inventory.
Known Problems TiCAP warning period does not default to 15 days After installing iCAP version 10.01 on HP Integrity Superdome 2, the temporary capacity expiration warning period is set to 0 days instead of the default 15 days (this can be confirmed by running the icapstatus command). This problem can be solved by running the icapmodify -w number_of_days command to set the warning period to the required value.
or: ERROR: The following low-level WBEM error occurred: Locking or unlocking the target failed. These errors result from contention for system resources from the various partitions in the complex. If you see these messages, retry the Instant Capacity operation.
• • Authorize the use of temporary capacity on requested activations (using the -t option). This allows the reserved usage rights across the complex to exceed the number of actual usage rights. Temporary capacity is charged only if the number of active cores exceeds the number of actual usage rights. If the failed partition remains inactive and the number of active cores does not exceed the count of actual usage rights, temporary capacity is not charged. You must be careful with this method.
IMPORTANT: Do not issue the above sequence of commands on any system that is the active Group Manager for the group, as it removes the GiCAP database entirely and leaves the group members in an orphaned state. icapmanage hangs when specifying illegal standby group manager When adding a standby Group Manager using the icapmanage -a -S command, you cannot specify a system to be a standby for itself.
Considerations when upgrading hardware on a Group Manager If you upgrade the hardware on a Group Manager system, you must preserve and restore the UUID and the partition information on the system. Removal of member from a group after reignite In some circumstances, attempting to remove a member from a group after reigniting one or more hosts on the member will fail. A workaround is to update the host list of the member, removing and re-adding the reignited hosts.
Software Requirements Every HP-UX and OpenVMS partition in an Instant Capacity system is required to have the Instant Capacity software installed and the icapd daemon running (on HP-UX systems), or the ICAP_SERVER process running (on OpenVMS systems). You must maintain the Instant Capacity software until all program requirements are fulfilled and until the system is no longer considered an Instant Capacity system. If you are using GiCAP, all systems must be running Instant Capacity version 9.x (or later).
IMPORTANT: For the most recent required patches, see the Instant Capacity Installation page on the HP Software Depot (search for “B9073BA”): http://www.hp.com/go/softwaredepot HP-UX 11i v2 Requirements and Dependent Products The following software is required for Instant Capacity version 10.x on HP-UX 11i v2: • • • • • • • HP-UX 11i v2 iCAP software bundle B9073BA (version 10.x) — On the 11i v2 Applications Software media, or download the most recent version from the HP Software Depot at http://www.hp.
• • If you have a virtual partitioned environment, the Virtual Partitions (vPars) software (bundle T1335BC) must be version A.05.01 or higher. vPars is available separately and is not included with the OE. (GiCAP only) The CIM Server configuration property sslClientVerificationMode must be set to a value of “optional” on all GiCAP Group Managers and on all OS instances of all member systems. (The CIM Server may need to be restarted if the property was not previously set to this value.
Usage Rights Requirement A system managed under the Instant Capacity program can include one or more components (core, cell, or memory) that are without usage rights. Before you can use these components, you must obtain additional usage rights. Usage rights can either be purchased from HP, or, if the system is a member of a GiCAP group, borrowed temporarily from another member of the group, as described in the HP Instant Capacity user’s guide for Version 10.x.
GiCAP Requirements Software and System Requirements To use Global Instant Capacity, all partitions on all servers in the group must be running Instant Capacity version 9.0 or later. The Group Manager must be an HP-UX system running Instant Capacity version 9.0 or later. GiCAP now uses SSL certificates when making remote connections, rather than SSH as in previous releases.
Communication between GiCAP member hosts and the GiCAP manager requires the CIM Server configuration property sslClientVarificationMode to be set to “optional” on all GiCAP member OS instances, the GiCAP manager, and any planned standby GiCAP manager. This configuration attribute is not dynamic and must be set using the -p option. You must restart the cimserver to set the value. For details, see cimconfig(1M).
Whenever the GiCAP software needs to exchange SSL certificates between hosts it will prompt for the root password so that it can exchange the certificates. If the GiCAP software needs to exchange SSL certificates it will remove any existing certificates with the same “Issuer” and “Subject” attributes as the certificates the GiCAP software wishes to install. WBEM does not allow the installation of certificates with the same Issuer and Subject as previously installed certificates.
To complete the repair you must either re-add the member to the group using a command on the active group manager similar to: icapmanage -a -m xyz:x,y,z -g One Or use: icapmanage -Q The icapmanage -Q command will not reestablish communication between the member host and any standby manager. If a standby manager is being used, you must specify the standby manager again with a command such as: icapmanage -a -S gm2.ba.ff.
