+===== Description =====
+A monitoring script to keep tabs on your HBAs.
+It can check they are
+  * Online
+  * Running at optimal speed
+  * Not getting errors
+  * Correctly multi-pathed
+It will also
+  * List SCSI devices
+  * List remote ports
+  * List multi-path info, even if you don't want it to generate alerts.
+Alerts are configurable, as are what information to display, and this can be defined at server level, using client-local.cfg (See comments in script, lines 22-25)
+Override variables are (With default value)
+  * CHECKSPEED=true     -- Check HBAs at optimal speed and alert if not
+  * CHECKONLINE=true    -- Check HBAs are online and alert if not
+  * CHECKERRS=true      -- Check for link errors and alert if not
+  * CHECKMPATH=true     -- Show multipath info and alert if path is down. (See MPATHFAILCOL)
+  * LIST_MPATH=true     -- List the multi-path info only. (No alerts, but will be ignored if CHECKMPATH is true)
+  * LIST_SCSI=true      -- List the SCSI devices
+  * LIST_REMOTE=true    -- List the remote ports
+  * ERR_YELLOW=3        -- Number of link errors for a yellow
+  * ERR_RED=100         -- Number of link errors for a red
+  * MPATHFAILCOL=yellow -- Colour of a multipath fail
+Some may notice that this script could probably have been much shorter, and simpler to create using Perl, but that would require me to learn enough Perl to do so.
+Anybody feeling energetic enough to redo it in Perl - knock yourself out.
+===== Installation =====
+=== Client side ===
+. Copy hba.ksh to ~$HOME/client/ext
+. Edit the ''client/etc/clientlaunch.cfg'' and insert the following text:
+  [hba]
+          ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg
+          CMD $HOBBITCLIENTHOME/ext/hba.ksh
+          LOGFILE $HOBBITCLIENTHOME/logs/hba.log
+          INTERVAL 5m
+=== Server side ===
+If you want to override some of the default variables in the script, add them to client-local.cfg under the appropriate label.
+  HBA:export CHECKERRS=false
+  HBA:export ERR_RED=20
+  HBA:export LIST_SCSI=false
+See Description above for more.

+===== Known  Bugs and Issues =====
+**PUBLIC SERVICE WARNING**
+I have not had the opportunity to test this script under all fail conditions!
+This means that there could be bugs that I am not aware of.
+If you spot any, please let me know, and I will see what I can do about it.
+No bugs known - at the moment.
+===== To Do =====
+Fix any bugs that come along.
+Features?
+No. I am done with this one for now. I leave it to the rest of the community to add any more features.
+===== Credits =====
+I am going to take the blame for this one.
+However, I am indebted to Kevin Kelly for giving me the idea.
+http://www.xymon.com/archive/2010/08/msg00016.html
+It was a great way to keep myself from going crazy on what was panning out to be a very slow and boring day. :-)
+===== Changelog =====
+  * **2010-08-11**
+    * Initial release
