This is a simple script that takes the information about a Dell
PowerEdge RAID Controller (PERC) from Dell OpenManage Server
Administrator and presents that information is a more succinct way
than omreport does. Its output is strongly influenced by ZFS's
zpool status command.
You need to have OpenManage Server Administrator installed.
Simply run the perc-status script. If omreport isn't in your
path, pass its location to the script with the -r command line
parameter.
You can limit the program's output to a single controller with the
-c command line parameter.
The -b command line parameter will show the bus protocol (SAS, SATA,
IDE, etc.) for each physical disk. Similarly, the -m parameter will
show each disk's model number.
A few examples of the script's output:

This script relies on the undocumented XML output from omreport.
Meanings of various things have been reverse engineered and are likely
to be incomplete.
In particular, device states and statuses are represented as plain integers in the XML. The script contains mappings for all of the values known to the author, but there are many values still unaccounted-for.
If you run the script and it shows a value of "Unknown" with a number
next to it, please email phil_g@pobox.com with the output of the
script and the output of omreport for the device in question. (If
in doubt about the specific device, simply capture the entire output
of omreport storage controller controller=_x_, where "x" is the
number of the controller to which the device is attached.)
