creating a 1 disk LUN

JOHN TURNER_2 — Tue, 03 Jan 2006 10:09:41 GMT

Is it possible to create a 1 disk LUN on an FC60, not using RAID, We are not concerned with striping or mirroring as this is a test bed.

If it's possible what sort of command would i be using to perform this work

cheers

amcfg -L : -d
-r 0

-d specifies the disk, -r 0 RAID0

John,

To the best of my knowledge, it is not possible to create a 1 disk LUN on an FC60. The FC60 expects either RAID1 or RAID5. There are no other options. Probably your best bet would be a two disk RAID1 config.

No, John, I don't think so. When you create the LUN, the amcfg command requires you to specify a RAID level of either 1 or 5, so there's no way to make it a JBOD.

John,

RAID0 *is* supported on the FC60.

John,

to be precise, you need firmware version HP08 or higher, then RAID0 is supported.
