Limitations and considerations for Hitachi NAS plug-in
The following considerations and limitations are applicable in a Hitachi NAS environment.
All snapshots are captured at a file system level, and those snapshots are in read-only mode.
The limit for any file system name is 255 characters, NFS export/SMB share name is 80 characters on the array. In the case of a snapshot name, the maximum length must be 256 characters.
Sometimes backup from snapshot and normal restore jobs are shown as partial success on the NetBackup activity monitor due to the NDMP file access permissions.
A file system of selected NFS export/SMB share must be in the Mounted state on the array, as Not mounted state file system affects the snapshot operations.
Hitachi NAS plug-in does not support point-in-time (PIT) rollback restore of shares using snapshots.
To upgrade NetBackup Snapshot Manager for Data Center from version 10.1 to later versions, you must expire all snapshots before starting the upgrade process.
