Managers,

Thanks to Bruce,Mandell Degerness and Benjamin C. Ingwersen for their
responses.

I will go to make two raids. One with 3 x 9.1Gb and another one with 3 x 9.1
Gb and later i will join the volumes with ADVFS Utilities (ADDVOL command).

Regards,

Fabio Ferreira

My memory may be failing, but I am pretty sure that you can create a RAID-5
volume group using all of the drives and then define 2 logical drives
(presented to the O/S), each smaller than 32GB. If you need a single file
system, you can then use LSM or AdvFS to combine the drives to make a single
volume again.

The kzpac only support luns less than 32gb. You can create a raid-5 unit
out of the 6 9gb disks and break it into 2 luns both less than 32gb. Using
the kzpac controller software the above can be done.

Managers,

I need to make a RAID 5 with 6 X 9.1 GB Ultra SCSI ( DS-RZ1DA-VW ) internal
on my AS 4100 466Mhz with Tru64Unix 4.0D.
The controller KZPAC-CB - Raid Controller with 8 Mb cache memory - suports
only 32 Gb. How can i make this RAID? What controller i can use?

Thanks,

Fabio Ferreira
