If the server originally was running
Cisco Unified Communications Manager release 5.x, perform a fresh
installation of the same 5.x release, then restore the data using
Disaster Recovery System, then go to the next step.
If the server was originally not running
Cisco Unified Communications Manager release 6.x or higher and the
switchover to release 8.6(1) occurred, then clean up disk space using the
procedure in the first step, then switch back to the previous release.
Order 146 GB hard drives.
When the new hard drives are ready to be installed, perform
these steps:
Perform a backup of the existing
Cisco Unified Communications Manager release using
Disaster Recovery System.
Install the new hard drives
Perform a fresh installation of the existing
Cisco Unified Communications Manager release.
Restore data to the server using
Disaster Recovery System.
Continue with upgrading the server.
Step 6
If the upgrade to release 8.6(1) fails for other reasons, contact
Cisco Technical Support.
Step 7
If the upgrade to release 8.6(1) succeeds, be sure to run
Real Time Monitoring Tool and monitor disk space usage, particularly if the
active partition found in this procedure was already over 97% disk usage.
Adjust logging
To change one of the values below, click the right mouse
button on the attribute and select Set Alert/Properties. Once in the dialog
box, click
Next to open the dialog box for modifying the
threshold values.
Before the upgrade:
Procedure
Step 1
Launch
Real Time Monitoring Tool.
Step 2
Select Alert Central, then perform the following tasks:
Select LogPartitionHighWaterMarkExceeded, note its value and
change its threshold value to 60%.
Select LogPartitionLowWaterMarkExceeded, note its value and
change its threshold value to 50%.
Polling occurs every 5 minutes, so wait for 5-10 minutes, then
verify that the required disk space is available. If you want to free up more
disk space in the common partition, change LogPartitionHighWaterMarkExceeded
and LogPartitionLowWaterMarkExceeded thread values to lower values (for
example, 30% and 20%) again.
After the upgrade finishes, change the threshold fields back
their original values. The defaults are 95% for high water mark and 90% for low
water mark.
