4–56 Compaq StorageWorks HSG80 Array Controller ACS Version 8.5 Maintenance and Service Guide
CLCP Utility
Use the CLCP utility to upgrade the controller software and the EMU software. Also use it
to patch the controller software. When installing a new controller, the correct (or current)
software version and patch numbers must be available. See Chapter 3 for more
information about using this utility.
NOTE: Only Compaq field service personnel are authorized to upload EMU microcode updates.
Contact the Customer Service Center (CSC) for directions in obtaining the appropriate EMU
microcode and installation guide.
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. When the cloning operation is done, back up the clones rather
than the storageset or single-disk unit, which can continue to service its I/O load. When
cloning a mirrorset, the CLONE utility does not need to create a temporary mirrorset.
Instead, it 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 you are cloning 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, it restores the
unit to its original configuration and creates a clone unit for backup purposes.
FRUTIL
Use FRUTIL to replace a failed controller (in a dual-redundant configuration) without
shutting down the subsystem. Also use this menu-driven utility to replace cache modules
and external cache batteries. See Chapter 2 for a more detailed explanation of how
FRUTIL is used during a replacement process.
IMPORTANT: FRUTIL cannot be run in remote copy set environments while I/O is in progress to
the target side due to host write and normalization (ACS V8.5P only).
