MDT-148947 Data Protection
From a protection perspective, a snapshot
of a volume group is a single-point-in-time
copy of the volume group member
volumes. Membership changes to the
volume group prevent snapshot recovery
operations, such as restore or refresh,
unless the volume group is returned to
the same membership state at the time
the snapshot was created. It is
recommended that you do not delete the
volumes removed from a volume group
until all the snapshots of the volume
group either expire or are removed
manually.
If there are still volume group snapshots,
the delete request for the volume returns
the following error: "The Volume <volume
name> (id: <unique id>) cannot be deleted
until all volume group snapshots taken
when this volume was a member of a
volume group expire or are manually
deleted." This error does not indicate the
name of the volume group that is needed
to delete the volume group snapshots so
the volume deletion can succeed.
In PowerStore, first identify the volume
group name, if it is unknown, by navigating
to Snapshots table of the removed member
volume. Volume group snapshots that have
been created by a protection policy should
have the volume group name as part of the
system-created snapshot name for each
member volume. If there are only manual
snapshots, you can use REST API to identify
the volume group name.
The volume group snapshots can be deleted
by navigating to the protection tab and
viewing the snapshots for the specific
volume group. Click Show/Hide Table
Columns and add the Volume Members
column. The column appears and displays a
number. When you hover over that number,
the volumes within the VG snapshot become
visible. You can look for a pattern by sorting
this column. A column with more members
might indicate that the VG snapshot has the
member that is preventing the volume
deletion operation, assuming one or more
members have been removed and
snapshots continued to be created on the
remaining VG members.
MDT-146780 Data Protection
When deleting a snapshot rule, the
snapshot rule may not appear to be
deleted, and the following error appears:
"The system encountered unexpected
backend errors. Please contact support.
(0xE0101001000C)". Do not continue
using the rule for protection.
Delete the snapshot rule again. The same
error appears, but the rule will be deleted.
MDT-117061 Hardware
When beginning cluster creation, the
hardware status is incorrectly indicated as
not configured for clustering.
Wait a few minutes and try again.
MDT-190232 Hardware
The svc_node shutdown command may
reboot the node instead of powering it
off.
Run the svc_node shutdown command
again when the node has finished rebooting.
MDT-137439 Import
If an import from a Unity or VNX2 system
to PowerStore is cancelled by the user or
fails for some reason, it is possible that
subsequent attempts to import the
volume will also fail.
Remove the Unity or VNX2 as a remote
system and then add it again. This action will
clear the issue and allow the import to
proceed.
