Chapter 4. Downgrading the Enterprise Virtual Array
Note
The software loads in parallel on the FC drive enclosures. During the software downgrade,
the EMUs on the FC drive enclosures might flash red LEDs and sound an alarm. After the
software downgrade completes, the flashing red LEDs and alarm sound cease. The process
of downgrading the enclosure software continues in the background after the controller
software is downgraded.
During the EMU firmware downgrade, all of the disk drives are listed in the Un mappable
Hardware folder and all of the disk enclosure bays disappear. The firmware downgrade can
take up to 10 minutes to complete. After the d owngrade has completed, the disk enclosure bays
are listed under the Disk Enclosure elements. The software loads on the HSV controllers. The
HSV controllers synchronize using the new software. The Scanning for disks message
on the cont
rollers’ OCPs indicates that synchronization is taking place.
