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 6.2 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 user name 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
.
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=
wwnType=
serverIdType=
serverIdEnd=<>
NOTE:
“-quiet” is an option to suppress user confirmation prompts. This option is useful for
scripting operations. This option is available for VC firmware 1.3x and later for the disable
account, remove the account, and release ranges commands.
2.
In Systems Insight Manager, perform a new discovery.
3.
Add the same VCEM license keys you were using previously and license the VC Domains with
the same key.
