A performance drop occurs when using DPM on a Microsoft
Windows system to back up to a Scalar 500i tape library. Change the DPM behavior to send one request at a time by adding DWORD
“BufferQueueSize” under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection
Manager\Agent, and set the value to 1.
Then restart DPM servers: MSDPM, DPMLA, DPMRA.
When attempting to add a LUN to a container, the error
message “Commit failed (db propagation).” is returned. If you are using Fabric OS version 6.3.x, you may be attempting to add a LUN
after you have reached the limit of 512 LUNs per initiator in a container.
Beginning with Fabric OS version 6.4.0, you will receive an error message that
informs you that the maximum limit has been reached.
In an HA cluster after failover, when using the cryptocfg
--
show -hacluster -all command, the failover status
displays on one cluster member, but does not display on
the other cluster member.
In this particular case, the correct status is displayed when group leader node
is queried. If the other node is queried, the status not consistent with the
actual HA status. To be sure of the correct status issue the cryptocfg --show
-
hacluster -all command on the group leader node.
