XtremIO: Native replication snapshot sets are not viewable
Summary: When trying to view snapshot sets created by native replication through the CLI and UI, a no matches found message displays.
Symptoms
Trying to view the snapshot sets created by native replication results in a no matches found message in both the CLI and UI:xmcli (tech)> show-remote-protection-snapshot-sets protection-session-id=1No matches foundxmcli (tech)> show-remote-protection-snapshot-sets protection-session-id=2No matches found
However, by checking the protection sessions, the snapshot sets are being created:xmcli (tech)> show-remote-protection-session protection-session-id=1 Name: <Remote protection session name> Index: 1 Replication-State: active Replication-State-Details: Replication-Direction: source_to_target Block-Access-Type: read_only Source-XMS-Id: Name: <XMS name> Index: 0 Source-Cluster-ID: Name: <Cluster name> Index: 1 Source-CG-Id: Name: <CG name> Index: 2 Target-XMS-Id: Name: <XMS name> Index: 0 Target-Cluster-ID: Name: <Cluster name> Index: 1 Target-CG-Id: Name: <CG name> Index: 1 Num-Of-Vols: 3 RPO: 60 Max-BW(MB/s): 0.000 Protection-Window-Num-Copies: 27 Protection-Window-Duration-in-Days: 4.000 Current-Protection-Window-Copies: 10 Source-Retention-Policy-ID: Name: <Retention policy name> Index: 1 Target-Retention-Policy-ID: Name: <Retention policy name> Index: 1 Number-Of-Target-PITs: 10 Target-Pit-Num-Copies-Status: ok Target-Pit-Window-Size-Status: protection_window_not_full Number-Of-Source-PITs: 2 Next-Scheduled-Cycle: xxxxxxxx Replication-Mode: async Lag: 30 BW(KB/s): 0 Max-BW(MB/s): 0.000 Transfer-Efficiency-Ratio(Ratio): 1 Cycle-Start-Time(Timestamp): Tue Sep 17 15:37:43 2019 Last-Cycle-Start-Time(Timestamp): Tue Sep 17 15:37:43 2019 Last-Cycle-Completed-Snapshot-Set: xxxxxxxxx Last-Cycle-Duration: 1 Last-Cycle-Link-BW(KB/s): 70086 Last-Cycle-Effective-Bandwidth(KB/s): 13981303 Last-Cycle-Transfer-Efficiency-Ratio: 199.48671427 Cycle-Number(Count): 910 Num-Missing-Short-Period-Snapshot-Sets: 14 Num-Missing-Middle-Period-Snapshot-Sets: 3 Num-Missing-Long-Period-Snapshot-Sets: 0 Target-Missing-Pits-Alert: enabled Test-Copy-Mode: False Snapset-Backup-Snapset-Index: [] Current-Command-Name: Current-Command-Status: none Replication-Session-Consistency-State: consistent Obj-Severity: information
Cause
A code bug that causes the Tasker process on the XtremIO Management Server (XMS) to stop working. This affects the auto_sync job run by the XMS and ultimately affects the way it gathers the native replication snapshot information from the array.
Resolution
Found that this is a code bug with the current software on the array, and as a workaround, the refresh can be performed through the CLI.
Additional Information
If rebooting the XMS does not work, perform the following POA:
Ensure that the customer is aware that performing XMS recovery results in loss of the performance data, and their tags. Once customer approval is given for XMS recovery, perform the following:
Run xms-recovery on both XtremIO Management Servers:
- dry run xms-recovery on source xms; then xms-recovery on source xms if dry-run succeeds.
- dry run xms-recovery on target xms; then xms-recovery on target xms if dry-run succeeds.
