v
Create and maintain a cabling diagram of the current SAN configuration. Keep
this diagram updated as you make configuration changes, and keep the cabling
diagram available for review.
v
Create and maintain a list of other components that are being used within the
cabling diagram (such as the host system, fibre channel switches, and other SAN
attachments).
v
Ensure that all ESMs are properly seated.
v
Ensure that all drives are properly seated.
v
Ensure that all SFP modules are properly seated.
v
Confirm fibre channel cable loop size. (IBM specifications call for at least 3-inch
cable loops, but it is recommended that you use 6-inch cable loops or longer.)
v
Ensure proper fibre channel cable management.
v
Ensure proper air flow and temperature for all components in your EXP810
storage configuration.
Note:
You can find details on many of these inspection and maintenance
responsibilities in the appropriate sections of this document.
In addition to these inspection and maintenance responsibilities, IBM also strongly
recommends DS4000 training for staff that supports DS4000 storage configurations.
Although training is not a part of the Health Check process, DS4000 training
reduces the potential for configuration problems and contributes to the overall
health of the system.
Powering
on
the
EXP810
When you turn on and turn off the EXP810, be sure to use the startup sequence in
this section.
Attention:
Before
you first power on the DS4000 storage subsystem with a newly
installed EXP810, you
must
perform the DS4000 controller firmware upgrade
described in Appendix A, “Upgrading the DS4000 controller firmware,” on page 135.
In addition, you might have to regenerate the premium feature key files to re-enable
the premium feature key that is enabled from the factory after the controller
firmware upgrade.
Turning
on
the
EXP810
This section contains instructions for turning the EXP810 on and off under normal
and emergency situations.
The following procedure covers two situations:
v
The entire storage subsystem has been shut down. (The main circuit breakers for
the cabinet are off.).
v
Some storage expansion enclosures are being powered on while others remain
online. (The main circuit breakers for the cabinet are on.) You might encounter
this if you are adding an additional storage expansion enclosure to increase
storage capacity.
