• Web Client. Device Manager Web Client provides two types of user interfaces, an HTML GUI and a Java™ GUI, for Device Manager functions. Web Client communicates with and runs as a client of the Device Manager server. The HTML GUI is a browser-based application that can be accessed from Web browsers. This GUI provides the windows and dialog boxes for features other than the storage subsystem management and user management features.
• Continuous Access XP: The Continuous Access XP feature enables the user to make backup copies of volumes in a different storage subsystem. For details, refer to the Continuous Access XP manual. • Continuous Access XP Journal: The Continuous Access XP Journal feature enables the user to asynchronously make backup copies of volumes between different storage subsystems.
• Snapshot XP: The Snapshot XP feature (for StorageWorks XP12000/XP10000 only) allows the user to make backup copies of volumes in the same storage subsystem. For details on Snapshot XP, refer to the HP StorageWorks Snapshot XP User Guide. • Storage group: A user-defined set of paths (LUNs) which can be manipulated as a group. Adding storage to an empty logical group renders that group a storage group. The LUNs in the same storage group must physically reside in the same storage subsystem.
Table 1-2 Syntax Conventions Font or Symbol How Used [ ] An item or items enclosed in brackets are optional. | Only one of the options separated by a vertical bar can be used at one time. ... Ellipses (...) indicate that the item or items enclosed in () or [] and which immediately precede the ellipses can be repeated.

2 Device Manager Operations This chapter describes Device Manager operations: • User groups and user access levels (see section 2-1) • Storage management operations (see section 2-2) • Subsystem and volume configuration operations (see section 2-3) • Data management operations (see section 2-4) • Link-and-Launch operations (see section 2-5) • Report operations (see section 2-6) • System security operations (see section 2-7) 2-1 User Groups and User Access Levels Device Manager provides two set
Table 2-1 Device Manager User Roles User Role Description Storage Administrator Configures and manages storage subsystems. Can access all Device Manager functions and resources, but cannot configure user accounts. Guest Can view all Device Manager resources. Local System Administrator Manages user accounts within a user group. Also performs operations on the users in the user group. Can use all Device Manager functions to access the resources assigned to the user group.
for each storage subsystem on which the LUN Scan is performed. This logical group is created in the LUN SCAN group of the Logical Groups object. Beneath the logical group, a storage group is created for each port and host, and all unregistered LUNs are placed in this storage group. The LUN scan also causes Device Manager to register unique hosts for all WWNs in the storage subsystem.
The cache logical partition function allows you to establish an environment in which I/O operations on a specific volume do not affect the processing performance of other volumes. For details, refer to the Disk/Cache Partition manual. Device Manager can display attributes of the cache logical partition function on the logical volume. You can set up the cache logical partition function from the physical view. For details about the physical view, see section 10-2-1. • Storage logical partition function.
is the default mode. High-speed mode provides faster access speed by using more processors to handle data access. However, high-speed mode limits the number of available ports to one port on the channel adapter (CHA) board. • Create/Delete LDEVs. Device Manager allows you to create new LDEVs and delete existing LDEVs on the StorageWorks XP1024/XP128 storage subsystem (see sections 10-4-3, and 10-4-4).
NOTE: The data management function must be installed and available on the storage subsystem. 2-4-1 Managing Data on the StorageWorks XP12000/XP10000 LUN Security. Device Manager allows you to perform the following LUN security functions on the StorageWorks XP12000/XP10000 storage subsystem: • Secure/Unsecure Volumes. Device Manager allows you to secure and unsecure volumes (LUNs) as needed (such as add host(s) to or remove host(s) from a host storage domain).
• Continuous Access XP. Continuous Access XP allows you to perform synchronous and asynchronous remote copy operations. • Business Copy XP. Business Copy XP allows you to perform local (subsystem-internal) copy operations that can provide up to nine copies of a primary volume (P-VOL). 2-5 Link-and-Launch Operations The Device Manager link-and-launch feature allows administrators to easily move across storage management software for a full view of their storage resources.

12 Troubleshooting This chapter describes Device Manager Web Client troubleshooting. • For general information on troubleshooting, see section 12-1. • For information on countermeasures, see section 12-2. • For information on warning messages output from Device Manager, see section 12-3. • For information on error messages, see section 12-4.
Table 12-1 General Troubleshooting Information Problem Description The File Download panel displays when you invoke the Java™ GUI. The Java™ Web Start software may have been previously installed and removed. When JWS was removed, the association between the file extension “.JNLP” and the JWS application may not have been removed. When the link to the .JNLP file is selected, the OS tries to run but does not find JWS.
Table 12-1 General Troubleshooting Information Problem Description The Dynamic Link Manager button is not displayed in the Host view. When HDLM is installed on the host, the Device Manager server receives notification from a Device Manager agent and recognizes that HDLM for Sun™ ® ® Solaris™ and HDLM for IBM AIX is installed in that host.
Table 12-1 General Troubleshooting Information Problem Description When Device Manager has not When you are using a Flex Copy XP environment with StorageWorks created a copy pair for an LDEV, BC is XP12000/XP10000, BC is displayed in Copy Type of an LDEV for a Flex Copy XP displayed in Copy Type for that LDEV. pair. For details on Flex Copy XP, refer to the HP StorageWorks External Storage XP User Guide for the XP12000/XP10000. The contents of a message are garbled in an English language environment.
For example, depending on hardware, the servers and HBAs may not recognize the LUNs using the subject port unless a specific host mode is selected for the port. For details on how to change the port settings, refer to the manual for the corresponding storage subsystem. The mode cannot be switched if a host is currently performing I/O operation with the LUNs of the port. To proceed, shut down the host, change the mode, and then reboot the host.
12-3-8 An Internal Volume Mapped to an External Volume Is Invalid An internal volume mapped with an external volume may become invalid when you delete an external volume or change a security setting. The following warning message displays: An assigned volume of External Storage XP may be invalid. Are you sure you want to continue? Check any changes. If you perform this operation, you may have to execute Disconnect Volume in Remote Web Console.
Confirm that all hosts have been added into the host view before running a LUN Scan. After LUN Scan, Device Manager creates new hosts that have WWNs associated with the LUNs and have not been added into the Host View. You will need to clean up these hosts after the attributes of them are updated when the Device Manager Agent reports information about them. Are you sure you want to continue? Check the list of hosts to make sure that all WWNs managed by Device Manager have been registered as hosts.
