Canceling Domain Maintenance
If the VC Domain Group currently has IGMP Snooping disabled and the administrator changes
the VC Domain 3.70 running in compatibility mode to enable both IGMP Snooping and IGMP
NoFlood, and then cancels the maintenance operation use the following workaround:
1.
Wait until VCM restores communication with VCEM. The communication is restored when you
are able to log into the VCM web interface.
2. Access the VCM GUI or CLI for the VC Domain that failed to cancel maintenance.
3. Select one of the following options to disable IGMP No Flood
•
From the VCM command line, telnet into VCM using an SSH connection such as SSH
[email protected], where xxx is the VC Domain IP address and enter set
igmp NoFlood=false
.
•
From VCM GUI, clear the Prevent flooding of unregistered multicast traffic check box.
4. Browse to the VCEM GUI and cancel the VC Domain Maintenance again.
Completing Domain Maintenance
If the VC Domain Group currently has IGMP Snooping enabled and the VC Domain 3.70 running
in compatibility mode has both IGMP Snooping and IGMP No Flood enabled and the administrator
disables IGMP Snooping in another VC Domain in the VC Domain Group and tries to complete
maintenance the 3.70 VC Domain is marked as a “configuration mismatch”. If the administrator
proceeds with the resynchronization process when prompted by VCEM, the failure will occur. Use
the following workaround if this situation occurs:
1.
Wait until VCM restores communication with VCEM. The communication is restored when you
are able to log into the VCM web interface.
2. Access the VCM GUI or CLI for the VC Domain that failed to complete maintenance.
3. Select one of the following options to disable IGMP No Flood:
•
From the VCM CLI—Telnet into VCM using an SSH connection such as SSH
[email protected], where xxx is the VC Domain IP address and enter set
igmp NoFlood=false
.
•
From the VCM GUI—Clear the Prevent flooding of unregistered multicast traffic check
box.
4. Browse to the VCEM GUI and complete VC Domain Maintenance for the VC Domain.
For more information, see Customer Advisory PI51599 entitled “VCEM is unable to manage VC
3.70 Domains in compatibility mode with IGMP NoFlood enabled.”
Using Expanded VLAN capacity with the Cancel VC domain Maintenance operation
Cancelling maintenance mode in VCEM will not revert the Expanded VLAN capacity configuration
back to Legacy capacity mode.
If you enable Maintenance Mode, change Legacy capacity to Expanded VLAN capacity, and then
click Cancel VC domain Maintenance, VCEM cannot revert back to Legacy capacity mode in the
VC domain. Instead, the VC domain displays the “Under maintenance” icon and VCEM fails to
complete or cancel the maintenance operation. To resolve this, see the procedure to delete the
domain in
“Using Expanded VLAN capacity ” (page 156) .
Using iSCSI boot configuration with IE10 in compatibility view
The iSCSI boot configuration web GUI is not supported in IE10 compatibility view. Use IE10 without
compatibility view to make changes to the iSCSI boot configuration.
