Notes

Note

• The input parameters consistency_group_id and enable_quick_mode were removed in version 3.4.0. These were deprecated due to internal API simplification and are no longer supported.

• Connection type gateway was removed starting from version 3.4.0. Please use an earlier version if you require this connection type.

• During automatic SVOL creation in a pair setup, the system provisions a single secondary host group/iSCSI target.

• For Create a snapshot pair

• 1. If the P-VOL is unnamed, the S-VOL will be assigned a name in the format smrha-[ldev_id]. If the P-VOL has a name, the S-VOL should use the same name. (Here, smrha stands for Storage Module Red Hat Ansible.)

• 2. Only VSP One B24, B26, and B28 support Thin Image Advanced.

• For Create snapshot pair with a new consistency group

• 1. If the P-VOL is unnamed, the S-VOL will be assigned a name in the format smrha-[ldev_id]. If the P-VOL has a name, the S-VOL should use the same name. (Here, smrha stands for Storage Module Red Hat Ansible.)

• 2. Only VSP One B24, B26, and B28 support Thin Image Advanced.

• For Split a snapshot pair

• 1. Splitting a snapshot pair will fail if the pair belongs to a consistency group.

• For Restore a snapshot pair

• 1. To restore a Thin Image and Thin Image Advanced pair, the pair must be in PSUS status. After restoration, the Thin Image Advanced pair remains in PSUS status, while the Thin Image pair changes to PAIR status.

• For Delete a snapshot pair

• 1. If the pair includes an SVOL, it is unmapped from the associated host group(s), iSCSI target(s), and NVM subsystem(s), and then deleted.

• For Delete Thin Image pairs by snapshot tree

• 1. Thin Image Advanced is not available for this task.

• For Assign floating snapshot pair

• 1. Thin Image Advanced pairs must have a PSUS status assigned.

• For Unassign floating snapshot pair

• 1. The SVOL is detached from the mapped host groups, iSCSI targets, and NVM subsystems, and then deleted.

• For Set retention period of an existing snapshot pair

• If your P-VOL and S-VOL are a new Thin Image (HTI) pair and the desired state is split, the workflow is

• 1. Create the new TI pair (from two unpaired volumes).

• 2. Split the pair to store snapshot data (so the snapshot is preserved and copy-on-write stops).

• For Set retention period of snapshot pair after split If your P-VOL and S-VOL are a new Thin Image (HTI) pair and the desired state is split, the workflow is

• 1. Create the new TI pair (from two unpaired volumes).

• 2. Split the pair to store snapshot data (so the snapshot is preserved and copy-on-write stops).

• For Set retention period of snapshot pair with auto split If your P-VOL and S-VOL are a new Thin Image (HTI) pair and the desired state is split, the workflow is

• 1. Create the new TI pair (from two unpaired volumes).

• 2. Split the pair to store snapshot data (so the snapshot is preserved and copy-on-write stops).

• For Deleting garbage data of all Thin Image pairs in a snapshot tree

• 1. Thin Image Advanced pairs do not support this task.
