Hi,
Thanks to

It was noted that TruCluster 5 is diff from ASE 1.5.
Advise is to go to TruCluster 5.1 rather than 5.0A
The website to read up is
http://www.tru64unix.compaq.com/faqs/publications/cluster_doc/cluster_50A/TCR50A_DOC.HTM
It was noted that
The cluster root domain cannot be an LSM volume. Because LSM mirroring
is not available for cluster root, use hardware RAID to mirror the root file
system.
In that case, I may be to replace that SCSI adapter with a 3-port Raid
Adapter and then mirror all the disks between the 2 Shared SCSI ExtStorage.
Regards
IvanHoe
