12 Click OK.
13 In the Mappings tab, assign mappings between the snapshot virtual disk
and the host that accesses the snapshot virtual disk.
14 To register the snapshot virtual disk with the host operating system, run
the host-based hot_add utility.
15 To associate the mapping between the storage array name and the virtual
disk name, run the host-based SMdevices utility.
Specifying Snapshot Virtual Disk Names
Choose a name that helps you associate the snapshot virtual disk and
snapshot repository virtual disk with its corresponding source virtual disk. The
following information is useful when naming virtual disks:
By default, the snapshot name is shown in the Snapshot virtual disk name
field as:
—
where sequence-number is the chronological number of the snapshot
relative to the source virtual disk.
The default name for the associated snapshot repository virtual disk that is
shown in the Snapshot repository virtual disk field is:
—R
For example, if you are creating the first snapshot virtual disk for a source
virtual disk called Accounting, the default snapshot virtual disk is
Accounting-1, and the associated snapshot repository virtual disk default
name is Accounting-R1. The default name of the next snapshot virtual disk
you create based on Accounting is Accounting-2, with the corresponding
snapshot repository virtual disk named as Accounting-R2 by default.
• Whether you use the software-supplied sequence number that (by
default) populates the Snapshot virtual disk name or the Snapshot
repository virtual disk name field, the next default name for a snapshot or
snapshot repository virtual disk still uses the sequence number determined
by the software. For example, if you give the first snapshot of source virtual
disk Accounting the name Accounting-8, and do not use the software-
supplied sequence number of 1, the default name for the next snapshot of
Accounting is still Accounting-2.
