Issue Description
the active storage controller. As a result, the storage controllers in the storage system might end up
with different versions of the low-level firmware.
SCOS-32283 On SCv2000 series and SC4020 storage systems, the Storage Center software might indicate that a
prior version of software is available to install after performing a Storage Center ISO update.
SCOS-19264 When updating a dual controller storage system, controller reset might occur because of multiple
Storage Center update requests occurring at the same time and performing the same function.
Fixed Issues Related to Replication and Live Volume
The following issues are fixed in Storage Center 7.3:
Table 24. Fixed Replication and Live Volume Issues in Storage Center 7.3.20
Issue Description
SCOS-2474 Deleting a copy/mirror/swap or replication during a controller failover might result in a situation that
prevents snapshot reservations from being removed.
Table 25. Fixed Replication and Live Volume Issues in Storage Center 7.3.11
Issue Description
SCOS-51239 After a Live Volume is converted to a replication, selecting the Replicate Storage to Lowest Tier
checkbox in the Edit Replication dialog box has no effect on the replication. Selecting the Replicate
Storage to Lowest Tier checkbox still works for replications that have not been converted to a Live
volume and converted back to a replication.
Table 26. Fixed Replication and Live Volume Issues in Storage Center 7.3.6
Issue Description
SCOS-50985 An automatic or manual Live Volume swap role might become stuck and require a controller reset to
complete.
Table 27. Fixed Replication and Live Volume Issues in Storage Center 7.3.2
Issue Description
SCOS-51183 A memory leak might occur on a Storage Center that is performing cross-platform replication over an
iSCSI connection with a PS Series storage array.
Table 28. Fixed Replication and Live Volume Issues in Storage Center 7.3.1
Issue Description
SCOS-47224 Write latency might increase for synchronous replications that have a sequential write I/O pattern.
SCOS-46819 On a storage system with Automatic Fail Over Live Volumes, a Live Volume fail over might cause an
error because IORP codes are not transferred back to the originating controller over IPC.
SCOS-46572 The source and destination volumes associated with a replication might become different sizes if the
source volume fails to expand due to Storage Center scalability limitations.
SCOS-45553 Storage Center might be able to manage replication volumes as physical drives.
SCOS-41191 When the Storage Manager Client is directly connected to a Storage Center, the option to delete a
volume associated with a Live Volume or Live Migration is displayed, but it is not supported.
SCOS-27263 The replication of volumes with many recovered (unmapped) pages might be slower than expected.
SCOS-18102 The status of a cross-platform replication partner changes to down when the number of snapshots
exceed 1025.
