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 5.3 data files in a Windows environment" at the HP SIM Information Library at http:// h18013.www1.hp.com/products/servers/management/hpsim/infolibrary.html. No HP-predefined ranges for MAC and WWN addresses in VC Domain Groups After upgrading VCEM 1.40, VC Domain Groups that were using HP-predefined ranges for MAC and WWN addresses will start using VCEM-defined ranges for new server profiles. VCEM 1.40 and later do not use HP-predefined ranges for MAC and WWN addresses. Cannot change the MAC/WWN/Serial Number ranges in Virtual Connect Manager when there are server profiles After removing the VC Domain from a VC Domain Group, you might not be able to modify the MAC, WWN, or Serial Number ranges in Virtual Connect Manager even after removing all server profiles from the VC Domain. This situation occurs because the MAC, WWN, and Serial Number ranges you entered when releasing the VC Domain from VCEM have addresses externally in use by server profiles under VCEM control. To correct the issue, reset the Virtual Connect Module, and make sure you enter MAC and WWN ranges defined as exclusion ranges in VCEM. From the Virtual Connect Manager user interface, select Tools→Reset Virtual Connect Manager. VCEM database is inaccessible or irretrievable with no backup, or VCEM file systems are corrupt with no backup Without a backup, the VCEM cannot restore to the original point. But the network and SAN configuration and assigned server profiles can be recovered from the Virtual Connect modules. Reinstall the VCEM to a fresh system, ensuring that the backup is well prepared on VCEM and its database on the new VCEM. For more information, see Backing up and restoring VCEM. To resolve this issue: 1. Install VCEM 1.20 in a fresh machine. 2. Break the external manager lock in all VC Domains that were previously managed by VCEM 1.20. To remove the external manager account: a. Telnet in to the Virtual Connect Manager using an SSH connection such as SSH [email protected], where xxx.xxx.xxx.xxx is the VC Domain IP address. b. To determine the username of the external manager account, from the Virtual Connect Manager command prompt, enter show external-manager. For this example, assume the user name returned was xyz. c. To disable the account, from the Virtual Connect Manager command prompt, enter set external-manager Username=xyz Enabled=false. Troubleshooting 95

No HP-predefined ranges for MAC and WWN addresses in VC Domain Groups
After upgrading VCEM 1.40, VC Domain Groups that were using HP-predefined ranges for MAC and WWN
addresses will start using VCEM-defined ranges for new server profiles. VCEM 1.40 and later do not use
HP-predefined ranges for MAC and WWN addresses.
Cannot change the MAC/WWN/Serial Number ranges in Virtual Connect Manager
when there are server profiles
After removing the VC Domain from a VC Domain Group, you might not be able to modify the MAC, WWN,
or Serial Number ranges in Virtual Connect Manager even after removing all server profiles from the VC
Domain. This situation occurs because the MAC, WWN, and Serial Number ranges you entered when
releasing the VC Domain from VCEM have addresses externally in use by server profiles under VCEM control.
To correct the issue, reset the Virtual Connect Module, and make sure you enter MAC and WWN ranges
defined as exclusion ranges in VCEM. From the Virtual Connect Manager user interface, select

VCEM database is inaccessible or irretrievable with no backup, or VCEM file systems
are corrupt with no backup
Without a backup, the VCEM cannot restore to the original point. But the network and SAN configuration
and assigned server profiles can be recovered from the Virtual Connect modules. Reinstall the VCEM to a
fresh system, ensuring that the backup is well prepared on VCEM and its database on the new VCEM. For
more information, see
Backing up and restoring VCEM
.
To resolve this issue:
1.
Install VCEM 1.20 in a fresh machine.
2.
Break the external manager lock in all VC Domains that were previously managed by VCEM 1.20. To
remove the external manager account:
a.
Telnet in to the Virtual Connect Manager using an SSH connection such as
SSH Administrator@
xxx.xxx.xxx.xxx
, where
xxx.xxx.xxx.xxx
is the VC Domain IP address.
b.
To determine the username of the external manager account, from the Virtual Connect Manager
command prompt, enter
show external-manager
. For this example, assume the user name
returned was
xyz
.
c.
To disable the account, from the Virtual Connect Manager command prompt, enter
set external-manager Username=xyz Enabled=false
.
