Supported NetBackup Snapshot Manager operations on Hitachi SAN array

NetBackup Snapshot Manager performs the following snapshot management operations on the Hitachi SAN arrays.

Table: Snapshot Manager for Data Center operations on EMC PowerStore SAN plug-in

opeSnapshot Manager for Data Centerration

Description

Discover assets

Snapshot Manager for Data Center discovers all the Logical Devices (LDEV) created on the storage array. The primary LDEV objects appear as disk assets. The secondary LDEV objects that are part of a Thin Image (TI) pair appear under snapshots.

One or more LDEV objects are grouped in a logical entity called pool. For the Snapshot Manager for Data Center Hitachi plug-in to work, you must create a pool named `flexsnap_pool` on the storage array.

The LDEVs that have "CMD" in their attributes and those without any logical unit number (LUN) mapped are not discovered.

Create snapshot

NetBackup takes a snapshot of all the LDEV objects that are attached to a hostgroup.

When Snapshot Manager for Data Center takes a snapshot, it performs the following actions:

  • Creates a new LDEV object of the same size as the original (base) LDEV.

  • Puts the base LDEV and the new LDEV into a Thin Image (TI) pair. The base LDEV is the primary LDEV and the new LDEV is the secondary LDEV.

  • Splits the TI pair to create a point-in-time snapshot of the base LDEV and then updates the snapshot LUN path to point to the secondary LDEV.

  • Attaches the snapshot to the same hostgroup where the base LDEV is attached.

A typical snapshot created by Snapshot Manager for Data Center has the following naming convention: NB<unique_21digit_number>

Delete snapshot

When Snapshot Manager for Data Center deletes a snapshot, it performs the following actions:

  • Deletes the snapshot.

  • Removes the LUN path to the secondary LDEV associated with the snapshot.

  • Deletes the secondary thin LDEV.

Restore snapshot

Snapshot Manager for Data Center performs a restore operation on a thin image snapshot of LDEV. All the data in the primary LDEV is overwritten by the data from the secondary LDEV.

Export snapshot

When NetBackup exports a snapshot, Snapshot Manager for Data Center searches for the target host based on the World Wide Name (WWN) or the iSCSI Qualified Name (IQN) specified in the export request. After the host is identified on the storage array, Snapshot Manager for Data Center updates the path attribute of the secondary LDEV with the target host, where the snapshot is to be exported. Once the target host is added to the secondary LDEV host ports, the exported snapshot is immediately visible on the target host.

Deport snapshot

When a snapshot deport operation is triggered, Snapshot Manager for Data Center removes the target host from the secondary LDEV path attribute. Once the target host entry is removed from the secondary LDEV host ports, the exported snapshot is no longer visible on the target host and the deport operation is complete.
