Examine the display to verify the following information:
⊇ ⊇
Controller SCSI target number should be 0
If the target number is not 0, use the following commands to set a SCSI target ID for
the controller:
SWXRC> SET THIS_CONTROLLER ID=0
SWXRC> RESTART THIS_CONTROLLER
⊄ ⊄
Cache condition should be GOOD
If the Cache condition is BAD then call your sales person for unit service or
replacement of the Cache module.
⊂ ⊂
Battery condition should be GOOD
If the Battery condition is LOW then allow the battery to charge with the subsystem
power on for at least 6 hours. The battery must be fully charged to protect the data in
the Write Back Cache. If the Battery condition is LOW after 6 hours of charging then
call your sales person for unit service or replacement of the Batteries.
NOTE
The subsystem can be configured with the Battery condition LOW
however the Write Back Cache cannot be initialized.
⊆ ⊆∈ ∈∉ ∉
License key should be VALID
If the License key is INVALID then enter the following:
SWXRC> RUN FLS
and follow the menu driven program to enable the license. You will need the WRITE-
BACK CACHE, RAID5, and MIRROR License Key page that is provided in the
subsystem documentation package.
2.4 Dual–Redundant Controller Configuration
An optional controller and cache can be added to the SWXRC-04 RAID Array on the same
host SCSI bus. This is called a dual-redundant controller configuration.
Dual redundant controllers offer automatic, intelligent failover of attached storage devices in
the event of a controller failure. Up to four SCSI targets and 36 SCSI devices can be
supported by the two controllers in a dual-redundant configuration
In a dual-redundant configuration, one terminal can set both controller configurations.
Installation procedures for the second controller can be found in Chapter 9 of the SWXRC-04
RAID Controller User’s Guide (EK-SMCS1-UG). After installation of both controllers, use
the CLI to define the controllers’ parameters in the following order from a terminal
connected to one controller:
Check the cache and battery conditions of the other controller using the following command:
SWXRC> SHOW OTHER_CONTROLLER FULL
