[cisco-voip] Unity connection system error

Tue May 18 11:33:05 EDT 2010

I cannot find a recovery disk specific for my setup...I found 7.1(3)
2000 and I have 7.1(3) 3000 as I remember...would this disk work??

Most 7.x and later UCOS servers will show the write cache in 'show
hardware'.  Basically if your server has a dedicated array controller
(ie 7835, 7845 with scsi or sas drives) it should have one.  There were
a few of the original 7835s that didn't ship with it but only a few.

Aside from helping to prevent filesystem corruption during power outages
the write caches greatly increase the io performance of the server.  

For anyone with an older server that has this write cache you may be
starting to see errors about the battery.  As with all batteries they do
eventually die and when the battery fails the write cache gets disabled,
performance drops through the floor, and you will have issues.

Yes I think it was a power outage problem...I will try the recovery disk
before going to the reinstallation

A question please...how would I know that the system doesn't have a
battery backed-up write cache....my server model is IBM 7825.

You need to boot off of the system recovery disk and run a manual file
system check.  Cross your fingers, and if you can get the system back up
you need to get a backup and plan to reinstall and restore.

If you don't have the recovery disk you can download it from cisco.com
<http://cisco.com/>  (get the latest one in either UC or CUCM downloads,
it's the same disk for both), it's a ~600Mb iso IIRC.

With any of these appliance servers it is vital that they are on a UPS,
particularly if the system doesn't have a battery backed-up write cache.

Dear all;

I have a unity connection server in production and today morning I found
it powered off "I did not know the reason till now" but when I try to
boot the system it gives me an error with the following:

***An error occurred during the file system check.

*** Dropping you to shell; the system will reboot

*** when you leave the shell.

Give root password for maintenance

(or type control-D to continue):

I don't know what is the root password (AFAIK the TAC only have
it)....anyone know how to recover that server...is reinstallation will
help??? Any workaround before going to the reinstallation?
