same time. VC Domain Group firmware mode is the firmware level in which a VC Domain Group
operates.
NOTE:
For GUI screens and buttons to perform the VC firmware updates described in the following
procedures, see
“Updating VC firmware” (page 22)
.
To update a VC Domain to VC 3.7x or later from VC 3.18 or earlier:
1.
Use VC Domain Maintenance to perform a firmware update to an intermediary version that
is supported by the new firmware first. For example, if the current VC Domain Group firmware
mode is 3.15 and the new firmware is 3.7x, update the firmware on all VC Domains from
the VC Domain Group to 3.5x or 3.6x.
2.
After the firmware for all VC Domains has been updated to 3.5x or 3.6x, upgrade the VC
Domain Group firmware mode to 3.5x.
NOTE:
VC 3.5x and VC 3.6x share the 3.5x VC Domain Group firmware mode. There is
no separate 3.6x VC Domain Group firmware mode.
3.
From the VC Domains page in the VCEM GUI, select all VC Domains (which have just been
updated to 3.5x or 3.6x) from the VC Domain Group and the VC Domain Firmware Update...
GUI button. Then use the VCSU to update the VC firmware for each of the selected VC Domains.
4.
Optional—Update the VC Domain Group firmware mode to 3.7x or later after the VC firmware
on all the VC Domains in the VC Domain Group has been updated to VC firmware 3.7x or
later.
The following steps are an alternate procedure to update from VC firmware 3.15-3.18 to VC
firmware 3.7x or the latest firmware version:
1.
Remove the entire VC Domain Group from VCEM.
2.
Update the VC firmware for all VC Domains directly to 3.7x or later.
3.
Recreate the VC Domain Group using the updated VC Domains.

“Creating a VC Domain Group” (page 43)

If you are using HP Matrix Operating Environment infrastructure orchestration to manage logical
servers attached to server profiles, some additional steps may be necessary after removing and
recreating the VC Domain Group. See the HP Matrix Operating Environment Infrastructure
Orchestration User Guide at

VCEM performance
VCEM can be temporarily unresponsive if the CMS is under heavy load operation due to other
products such as Matrix OE. If this occurs the following message is displayed:
This action cannot be performed because the current user does not have
the required privileges.
To resolve this situation, wait until the CMS load is lighter and perform the operation again.
