Table 41. Known replication issues
Issue Description Workaround
50268 Rarely, replication schedules and replication operations do
not initiate after modifying an iSCSI CHAP secret. This
issue is due to the queued replication getting stuck, causing
replication sets to remain in a continuous Ready state and
preventing future replications from occurring.
Stop the replication, then clear the replication
queue using theclear replication-queue CLI
command.
NOTE: This issue is fixed in GT280R004-01
firmware.
49750 With I/O running, shutting down a controller immediately
after initiating an add disk group action can cause a
controller to stop responding.
None needed. The controller module restarts
automatically.
NOTE: This issue is fixed in GT280R004-01
firmware.
49722 The create snapshots CLI command allows one or more
spaces to be set as a snapshot name.
None.
NOTE: This issue is fixed in GT280R004-01
firmware.
49705 With single-controller mode enabled and I/O running, using
the CLI to change the cache write policy of a volume to
write-through can cause the controller to crash.
Quiesce I/O before changing the write policy for a
volume in a single-controller mode.
NOTE: This issue is fixed in GT280R004-01
firmware.
49412 In the CLI, the delete host-group command interprets
the host-group name d or D as an abbreviation for the
parameter delete-hosts.
Use the delete hosts command instead.
NOTE: This issue is fixed in GT280R004-01
firmware.
49209 In rare cases, a controller module can fail while running
scheduled replication.
None needed. The controller module automatically
restarts.
NOTE: This issue is fixed in GT280R004-01
firmware.
49181 In rare cases, a replication operation can fail with
the message Error: The requested operation
is not allowed for the current state
of the virtual replication set. An attempt
to resume replication fails with the message Error:
The operation cannot be completed because
controller failover or recovery is in
progress.
Restart the controller modules in the secondary
system. Restart each controller module individually to
maintain system availability.
NOTE: This issue is fixed in GT280R004-01
firmware.
49020 When a volume-copy operation is in progress, trying to
delete the destination volume causes the improper message
Wait for the volume-copy operation to finish, and
