Replacing a Disk Module
71
6.
Remove and store the ESD wrist band, if you are using one.
The SP formats and checks the new module, and then begins to reconstruct
the data. While rebuilding occurs, you have uninterrupted access to
information on the physical disk unit.
The default rebuild period is 4 hours.
Note:
During the rebuild period, performance might degrade slightly,
depending on the rebuild time specified and on I/O bus activity.
For more information on changing the default rebuild period, see “Binding
Disks Into RAID Units” in Chapter 4.
Updating the Disk Module Firmware
After replacing a failed unbound disk module (A0, B0, C0, or A3), update the
firmware on the CHALLENGE RAID SP. Follow these steps:
1.
Quiesce the bus, disabling all applications. Make sure that only the
RAID agent is running.
2.
Type as root:
raid5 -d device firmware /usr/raid5/flarecode.bin
Caution:
You must use this command every time you replace a failed
unbound disk module (A0, B0, C0, or A3).
The image in the file given in the command contains microcode that runs on
the SP and also a microcode image destined for the SP PROM, which runs
the power-on diagnostics.
