CLONE utility
Use the CLONE utility to duplicate the data on any unpartitioned single-disk unit,
stripeset, mirrorset, or striped mirrorset. Back up the cloned data while the actual
storageset remains online. After the cloning operation is done, back up the clones
rather than the storageset or single-disk unit, which can continue to service the I/O
load. After cloning a mirrorset, the CLONE utility does not need to create a
temporary mirrorset. Instead, the CLONE utility adds a temporary member to the
mirrorset and copies the data onto this new member.
The CLONE utility creates a temporary, two-member mirrorset for each member
in a single-disk unit or stripeset. Each temporary mirrorset contains one disk drive
from the unit being cloned and one disk drive onto which the CLONE utility
copies the data. During the copy operation, the unit remains online and active so
the clones contain the most up-to-date data.
After the CLONE utility copies the data from the members to the clones, the
CLONE utility restores the unit to the original configuration and creates a clone
unit for backup purposes.
