Collection Volumes Panel Table 133. Collection Volumes Panel Field Volume Storage pool Reported size Volume reserve Status Replication partner SyncRep status iSCSI connections Description Name of the volume within the selected collection Storage pool to which the volume belongs Maximum amount of space for the volume that the group can allocate to the volume Actual amount of pool space that the group has allocated to the volume. The value of the volume reserve depends on whether you enable thin provisioning on the volume. Volume collection is online or offline. An iSCSI initiator can discover or connect to an online volume only. Name of the replication partner for the volume. Only a replication partner is listed if replication has been configured for the selected volume. Status of the volumes for which SyncRep has been enabled: • In Sync - SyncActive and SyncAlternate pools contain the same volume data. • Paused - Administrator has paused synchronous replication. While synchronous replication is paused, the volume is still online, and initiators can connect to and write to the SyncActive volume, but changes to the SyncActive volume are not propagated to the SyncAlternate volume until SyncRep is resumed. An administrator can pause and later resume synchronous replication. • Out of Sync - The SyncActive and SyncAlternate volume might not contain the same volume data; the SyncActive pool contains the most recent volume data. A volume can become out of sync if synchronous replication is paused, or if one of the pools becomes unavailable or has no free space. The volume can become out of sync when the snapshot reserve in the SyncAlternate pool is full, but only when the snapshot space recovery policy sets volumes offline when the snapshot reserve is depleted. NOTE: As an example, this situation could happen in a maintenance window during which the SyncAlternate pool is taken offline. If data is written to the volume while synchronous replication is paused, it is written only to the SyncActive pool, and the two pools are out of sync. The group tracks all volume writes while synchronous replication is paused and, when the administrator resumes synchronous replication, writes the tracked changes to the SyncAlternate pool. Number of iSCSI initiators connected to the volume NOTE: You can sort the table by clicking the column headings. The table is sorted by volume name by default. Component Versions Panel Table 134.

Collection Volumes Panel
Table 133. Collection Volumes Panel
Field
Description
Volume
Name of the volume within the selected collection
Storage pool
Storage pool to which the volume belongs
Reported size
Maximum amount of space for the volume that the group can allocate to the volume
Volume reserve
Actual amount of pool space that the group has allocated to the volume. The value of the
volume reserve depends on whether you enable thin provisioning on the volume.
Status
Volume collection is online or
offline.
An iSCSI initiator can discover or connect to an online
volume only.
Replication partner
Name of the replication partner for the volume. Only a replication partner is listed if
replication has been
configured
for the selected volume.
SyncRep status
Status of the volumes for which SyncRep has been enabled:
In Sync — SyncActive and SyncAlternate pools contain the same volume data.
Paused — Administrator has paused synchronous replication. While synchronous
replication is paused, the volume is still online, and initiators can connect to and write to
the SyncActive volume, but changes to the SyncActive volume are not propagated to
the SyncAlternate volume until SyncRep is resumed. An administrator can pause and
later resume synchronous replication.
Out of Sync — The SyncActive and SyncAlternate volume might not contain the same
volume data; the SyncActive pool contains the most recent volume data. A volume can
become out of sync if synchronous replication is paused, or if one of the pools
becomes unavailable or has no free space. The volume can become out of sync when
the snapshot reserve in the SyncAlternate pool is full, but only when the snapshot
space recovery policy sets volumes
offline
when the snapshot reserve is depleted.
NOTE: As an example, this situation could happen in a maintenance window
during which the SyncAlternate pool is taken
offline.
If data is written to the
volume while synchronous replication is paused, it is written only to the
SyncActive pool, and the two pools are out of sync. The group tracks all volume
writes while synchronous replication is paused and, when the administrator
resumes synchronous replication, writes the tracked changes to the
SyncAlternate pool.
iSCSI connections
Number of iSCSI initiators connected to the volume
NOTE: You can sort the table by clicking the column headings. The table is sorted by volume name by default.
