HP StoreAll Storage - Manual (Page 98)

The type of storage array determines the maximum number of snapshots you can keep and mount
per file system.
Maximum number of snapshots to mount Maximum number of snapshots to
keep Array
7 snapshots per file system 32 snapshots per file system P2000 G3 MSA System/MSA2000
G2 array
7 snapshots per file system 8 snapshots per file system EqualLogic array
For the P2000 G3 MSA System/MSA2000, the storage array itself also limits the total number of
snapshots that can be stored. Arrays count the number of LUNs involved in each snapshot. For
example, if a file system has four LUNs, taking two snapshots of the file system increases the total
snapshot LUN count by eight. If a new snapshot will cause the snapshot LUN count limit to be
exceeded, an error will be reported, even though the file system limits may not be reached. The
snapshot LUN count limit on P2000 G3 MSA System/MSA2000 arrays is 255.
Creating automated snapshots using the GUI
On the Filesystems page of the management console GUI, select the file system where the snapshots
will be taken and then, in the Navigator, select Snapshots. When the Snapshots page appears,
click Create.
On the General tab, select Recurring as the Snapshot Type. Then, click New to create a new
snapshot scheme. The Create Snapshot Scheme dialog box appears.
