RAID Array 450 HSZ50 HSOF Software Version 5.7 for Compaq Tru64 UNIX Release Notes

Release Notes
AA–R1ZZE − TE Page 15
4.3 Action for Repeated Reboot Problem Resolution
Very rarely, a hardware failure might cause a controller to reboot repeatedly,
preventing preferred disk devices from completing failover to the other
controller. HSOF Version 5.4 contains a modification so that if the same
bugcheck repeats itself three times in a ten minute period, the controller will
shutdown with no restart to permit the disk devices to failover to the working
controller in a dual-redundant pair.
4.4 Support for Large Drive Formatting
The V5.4 release supports formatting of large disk devices (9 GB and 18 GB).
4.5 Support for up to Fourteen 18 GB Drives
The maximum storageset size has been increased to 256 GB so that the
controller can support up to fourteen 18 GB drives.
