Raid A1000 with E450 and E250.
Hi,
I'm facing problem in connecting a Raid A1000 to E250 and E450. ( Both machines with Solaris 2.6 OS and patched, with different
scsi-initiator-ids - 7 & 3 ).
BTW, I'm not using this setup to access raid data from both machines simultaneously. There is Veritas Cluster Server monitoring these devices and if any one fails, the VCS will mount the raid device in the standby machine.
If either of E250 or E450 is down, the other machine works well with the Raid Box. When the second machine boots up, it gives scsi errors and even if it boots, it hangs in 'format' command. Even the rm6 configuration GUI hangs.
The E250 identifies the raid device as C1t5 and E450 identifies as C2t5 (because c0 is used for internal disks and c1 is used for tape and Cdrom drive). Is this causing the problem ??
Is there any way to make E450 to identify the raid device as C1t5 ?
( The raid device ( single controller, raid manger 6.22 ) is connected via PCI slot )
Thanks in Advance,

Hi guys,
I was asked to setup an Ultra60 (Sol 8) with an StorEdge A1000. Does anyone know if a probe-scsi-all is suppose to detect it? Right now it doesn't, so maybe I answered my own question :rolleyes:

WIPEFS(8) MAINTENANCE COMMANDS WIPEFS(8)
NAME
wipefs - wipe a filesystem signature from a device
SYNOPSIS
wipefs [-ahnp] [-o offset] device
DESCRIPTION
wipefs allows to erase filesystem or raid signatures (magic strings) from the device to make the filesystem invisible for libblkid. wipefs
does not erase the whole filesystem or any other data from the device. When used without options -a or -o, it lists all visible filesys-
tems and offsets of their signatures.
OPTIONS
-a, --all
Erase all available signatures.
-h, --help
Print help and exit.
-n, --no-act
Causes everything to be done except for the write() call.
-o, --offset offset
Specifies location (in bytes) of the signature which should be erased from the device. The offset number may include a "0x" prefix,
and then the number will be read as a hex value. It is possible to specify multiple -o options.
-p, --parsable
Print out in parsable instead of printable format. Encode all potentially unsafe characters of a string to the corresponding hex
value prefixed by 'x'.
