Disk Space Low Warning When Upgrading From SAN Volume Controller V5.1.0.x to V6.x
A 'Disk Space Low' warning may be seen in the SVC Console when upgrading a SAN Volume Controller cluster from V126.96.36.199 or V188.8.131.52 to V6.x
The SAN Volume Controller software automatically checks the amount of disk space available for upgrade packages on the configuration node. A warning message is displayed on the Upgrade Software panel in the SVC Console (GUI) when disk space is low.
The V184.108.40.206 and V220.127.116.11 releases do not account for the larger file sizes of the V6.x upgrade packages and may display a low disk space warning after the upgrade package has been uploaded to the cluster.
Resolving the problem
This warning can be safely ignored. The warning threshold was updated in V18.104.22.168 release of the SAN Volume Controller software.
