UCCX 8.5.1 fix for CSCtj97676 - Disk I/O Timeout w/SAN

Anyone know when this is corrected with UCCX 8.5.1, if it is? 

The bug only lists Call Manager versions with fix, and I have that info already but it doesn't mention versions for other applications (UCCX, CUC, etc). I've opened a TAC case a few days ago and gave them this bug id for reference but nothing yet.

CSCtj97676 Bug Details

UC Applications that use SAN storage need ability to change disk timeout

Symptom:

When deploying UC applications within a virtualized environment, the SAN

vendors require certain disk timeout settings to be applied to hosts/virtual

machines. However, installing vmware tools in either ESX4.0 or 4.1 does not

properly update the disk timeout in the redhat version 4, which used for UC

applications. Vmware is suggesting a value of 180 seconds, which seems well

within most SAN vendors recommendations that are typically used.

The current timeout value used in UC application is 30 seconds.This needs to be

changed to 180 seconds. With the current default value of 30 seconds, some SAN

events (controller failures, etc) will inadvertently cause the linux file

system to go into a read-only state. This could cause a major UC outage.

Conditions:

This is applicable only for UC applications within a virtualized environment

using SAN.

Workaround:

None

UCCX 8.5.1 fix for CSCtj97676 - Disk I/O Timeout w/SAN

Hi Ebergquist,

I do not see any UCCX specific versions mentioned here as part of the fix. TAC might help you to get that information

However this defect was verified with the below details.

This verification was completed with UCS Host using ESXi 4.1/VM having VMware tools installed 
Timeout is set to 180

Hope it helps.

Anand
