back to active mode. Once you have done that, you might have to do some LUN
rebalancing between the active controllers now. Also check to make sure that the
firmware level matches what was on the active controller; you might have to do a
firmware upgrade on the replaced controller.
If you are going to use the rdacutil -u/U to unfail the controller, and use the
device argument form, you must use the controller that is in active mode and not the
failed controller device name. The -U option will not do any checks and will just try
to bring the controller back online through brute force.
It has been reported from the field that sometimes during a boot -r that one of the
controllers might be thrown into a reset (failed) mode. Because of this, if you are
adding a new A3x00 or moving them around, that /dev/dsk or /dev/rdsk will not
get built for the controller held in reset mode.
The simplest way to resolve this is to do the following:
■ Do a module profile on that A3x00 and get the cAtBdCsD for that good controller.
■ Execute rdacutil -u cAtBdCsD.
■ Once it is completed, do another module profile and make sure that the controller
that was held in reset is active. If it is in passive mode go through the
maintenance application and make it active.
■ Execute boot -r and the paths for that controller that was held in reset mode
will now be built.
■ Once the system is back up, execute a lad and a healthck -a.
Note – At this point, you might want to do some LUN balancing now that both
controllers are in active mode.
6.1.4 Additional ASC/ASCQ Codes
ASC/ASCQ 0x3f/02 is not documented in either the LSI Software Interface
Specifications on the engineering web page or in the online file
/etc/raid/raidcode.txt. These codes are reported by the backend disk drives in the
array. These ASC/ASCQ codes can appear on the controller console, as viewed
through the serial ports. The message might look like:
The additional ASC/ASCQ codes are the following:
interrupt: NOTE: interrupt: 00000000 29 00 00 00 0000interrupt:
