HP Virtual Connect Enterprise Manager Software - Manual (Page 130)

Performing the VC Domain maintenance operations with forward-compatible
VC firmware
If you have a VC Domain running in a VC Domain Group with VC firmware 3.3x, VC Domains
that do not support the 3.3x firmware (like a future VC firmware) cannot be added into this VC
Domain Group.
If you begin a VC Domain maintenance operation (from VCEM) on one of the VC Domains within
the VC Domain Group to start a firmware upgrade operation, while the VC Domain is under
maintenance, the whole VC Domain Group and all the VC Domains in it are blocked for profile
operations.
If you upgrade the VC Domain to a new VC firmware that does not support backward compatibility
with VC 3.3x, and then use VCEM to complete VC Domain maintenance, the complete maintenance
operation fails because the new VC Domain firmware is not compatible with the current VC Domain
Group 3.3x firmware. Select from one of the following options to resolve this:
•
Remove the updated VC Domain from the 3.3x VC Domain Group and create a new VC
Domain Group using the VC Domain that was removed from the 3.3x VC Domain Group.
•
Use VCSU 1.7.0 or later to revert back to the previous VC firmware version without losing
data.
General
If you are logged into HP SIM using an account with insufficient access privileges and attempt to
execute the “VCEM Profile Failover by Hostname”, or “VCEM Profile Failover by IP address” custom
tools, the following message appears:
SSH public key authentication failed for user
To resolve this issue, log in to HP SIM with an account created with VCEM Domain Group Limited
Operator or higher permissions for the resource being managed and execute the VCEM Profile
Failover by Hostname or VCEM Profile Failover by IP address custom tools again.
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.
VC Domain Groups and VC Domain Management
•
At times the network port speed configured as 10 Gb on a VC Domain that supports 10 Gb
incorrectly displays as Auto on a VC Domain that does not support 10 Gb.
This situation occurs when the Virtual Connect Manager user interface on the VC Domain
without the SFP-SR connector displays the network speed as Auto.
The Auto value appears only on the Virtual Connect Manager user interface. When VCEM
attempts to capture the network configuration from VCM, the information returned is 10Gb
and not Auto.
To resolve this issue:
1.
Access the VCM user interface on the VC Domain that does not have the SFP-SR connector.
2. Edit the network with the incorrectly labeled Auto port speed to use another port speed
value (for example, 1 Gb).
3. Save the edits.
