Installation Procedures for an SF72-UK
Upgrade Kit
B.1 Introduction
This procedure allows the SF72-UK upgrade to be performed while the
host system and the disk ISEs in the SF72-HK storage enclosure are
off-line. Refer to Section B.2 for instructions on how to take a disk ISE
off-line.
To ensure the integrity of the host system, follow the steps in this
procedure in order and exactly as instructed.
NOTE
You must upgrade the two-drive SF72-HK to contain four drives
before adding any other SF72 storage enclosures on that bus of
the SF200 storage array.
Only one SF72-HK SF72 storage enclosure can exist in an SF200
storage array at one time.
