Sorry, Tiago. I misread your email regarding the two volumes: RAID0 and
In the following messages:
"Port 1 .. Member disk(0,1)" means that the hard drive attached to port
0 (scsi address: 1:0:0:0) is a member of two RAID arrays (RAID0 and
RAID1) which are defined as RAID id 0 and 1 respetively.
But port 0(scsi address 0:0:0:0) has a hard drive that has a RAID
configuration including the same names of the RAID arrays.
Because the metadata got messed up, OROM couldn't determine that the
above two hard drives were belong to the same group of disks. In order
to differentiate the names of the RAID volumes from two hard drives, :1
was added in.
>>> >0 RAID0:1 80Gb Failed
>>> >1 RAID1:1 109.0Gb Degraded
>>> >2 RAID0 80Gb Failed
>>> >3 RAID1 109.0Gb Degraded
>>> >0 Hitachi 149.1GB Member Disk(0,1)
>>> >1 Hitachi 149.1GB Member Disk(2,3)
Thanks Eric for pointing out that the OROM display screen doesn't
include the partition information.
I hope that will help you understand those magic numbers. If you have
any questions, let me know.
