Hi Fabio

Even better is to create a raidset of the 6 disks and the controller will
partition it to 32Gb and TheRest.
You can the use addvol to join the two partitions presented as two disks to
form one 45Gb raidset rather than 2x 18Gb raidsets if you so wish.

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
