NOTE: You must schedule downtime for the clusters and applications during an
upgrade because an online Dell PowerVault MD3000i storage array controller
firmware upgrade is not supported in a Dell PowerEdge Cluster configuration.
Issues Faced When Upgrading the Dell™ PowerVault™ MD3000i Storage Array
Controller Firmware in a Dell PowerEdge™ Cluster Configuration
• Cluster(s) and application(s) using the virtual disks on an PowerVault
MD3000i storage array may fail while performing an online upgrade of the
storage array. Access to the virtual disks on the PowerVault MD3000i may
be temporarily lost.
To resolve this issue you must take the cluster nodes offline before
upgrading the PowerVault MD3000i storage array controller firmware.
• You must reboot the cluster node(s) to be able to access the virtual disks.
Dell is working with its partners to resolve this issue.
