IBM DCS3860, Инструкция по установке, использованию и обслуживанию

v
For the DCS3860, enable the read/write cache. In addition, use the Storage
system Profile to make sure that cache is matched between the controllers.
Set a regular schedule of periodic health check evaluations to keep the firmware
levels current and to preserve optimal data access and performance.
Hardware inspection
You must regularly inspect hardware components to ensure optimal performance
of the storage system. For best results:
v Maintain an up-to-date storage system profile for the storage configuration. Save
the profile to a server disk that will remain accessible in case of a DCS3860
storage configuration failure. Do not save the profile only to a LUN in the
storage system.
v
Develop a change-management plan. The plan should include schedules for
updating system firmware and server host software.
Note: Some updates might require storage system downtime.
v
Use only IBM-approved cables. If any of the cables are not IBM-approved, note
this down in the configuration document.
v Create and maintain a cabling diagram of the current 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 and other attached devices).
v
Ensure that all controllers and ESMs are correctly seated.
v
Ensure that all drives are correctly seated.
v
Ensure that cables are managed correctly.
v
Ensure proper air flow and temperature for all components in the storage
configuration.
In addition to these inspection and maintenance responsibilities, conduct training
for staff that support storage configurations. Although it is not a part of the health
check process, training reduces the potential for configuration problems and
contributes to the correct operation of the system.
Powering on the DCS3860
This section contains instructions for turning on the storage system under normal
situations. “Turning off the storage system” on page 70 contains instructions for
turning off the storage system under normal and emergency situations. When you
turn on and turn off the storage system, ensure that you follow the startup
sequence that is described in this section. If you are turning on the storage system
after an emergency shutdown or power outage, see “Restoring power after an
unexpected shutdown” on page 73.
While performing this procedure, you must remember that:
v
The entire storage system has been shut down (the main circuit breakers for the
rack are off).
v
Some storage enclosures are being powered-on while others remain online (the
main circuit breakers for the rack are on). You might encounter this if you are
adding an expansion enclosure to increase storage capacity.
