Cannot manage a VC Domain when VC module failover is taking place
VCEM cannot create a VC Domain Group or add a VC Domain to a VC Domain Group when a
backup VC module is discovered or if a failover of a VC module occurred in a redundancy
environment. The following error message appears:
"The VC Domain [VC Domain Name] cannot be managed by VCEM. A possible
cause is that the current state of the VC Domain is unknown. Verify HP
Systems Insight Manager (Systems Insight Manager) is referencing the
primary VC Module. If not, run Systems Insight Manager discovery to
update the reference."
To correct this issue, perform an Systems Insight Manager discovery on the Onboard Administrator
IP address associated with the VC module and perform the VCEM operation again.
VC Domain displays Missing External Manager lock status
If the VC Domain displays a status of Missing External Manager lock icon, the external manager
lock has either been suspended or removed.
To correct this issue with a VC Domain, remove the VC Domain from VC Domain Group, break
the external manager lock and release these MAC, WWN, and serial number address ranges as
follows:
1.
Telnet in to the VCM using an SSH connection such as SSH Administrator@xxx.xxx.xxx.xxx,
where xxx.xxx.xxx.xxx is the VC Domain IP address.
2. To determine the user name of the external manager account, from the VCM command prompt,
enter show external-manager. For this example, assume the user name returned was
xyz
.
3. To disable the account, from the VCM command prompt, enter
set external-manager Username=xyz Enabled=false .
Perform the following:
•
To remove the account and release the VC Domain from VCEM control, from the VCM
command prompt, enter
remove external-manager Username=xyz
mactype=<Factory-Default/User-Defined> MacStart=<> MacEnd=<>
wwnType=<Factory-Default/User-Defined> WwnStart=<> WwnEnd=<>
serverIdType=<Factory-Default/User-Defined> serverIdStart=<>
serverIdEnd=<>
NOTE: The “-quiet” option is used to suppress user confirmation prompts. This option is useful
for scripting operations. This option is available or later for the disable account, remove the
account, and release ranges commands.
For more information, see the HP Virtual Connect Manager Command Line Interface User Guide.
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” (page 58) .
