<DIV><FONT face=Arial size=2>I've been doing a little thinking about this.
One problem is Brandon doesn't mention at what level he is observing the drive
status, OS or BIOS (System or controller). He also doesn't mention if this
is a raid 0, 1 or 5, combination or jbod.</FONT></DIV>
<DIV><FONT face=Arial size=2>I'm going to assume raid 5 here. If this is
an older raid controller, you will probably have to go into the bios for the
raid controller and designate that the drive is part of the array and tell it to
rebuild the stripe if it doesn't automatically do this.</FONT></DIV>
<DIV><FONT face=Arial size=2>Another issue might be is whether the drive's
geometry/storage size falls short of the others and can't hold it's portion of
the stripe. If the drive is larger than the others, then most controllers
will only make use of enough space to match the other drives.</FONT></DIV>
<DIV><FONT face=Arial size=2>But you can't make use of any of the unused
space. In some cases you have to have a drive that matches the geometry of
the others, no allowances. Before you reboot, make sure as to whether or
not you are using hardware or software (OS based) raid. If it is software
based, don't reboot until you've verified that the drive is part of the array
and the stripe is rebuilt. If you reboot you may screw yourself depending
on the implementation. If this is harware based raid, you're probably
going to have to reboot thus taking the machine offline unless you have agent
software loaded that can talk to the raid controller and accomplish the needed
tasks. Hope this helps.</FONT></DIV>

storagetek/clariion array</DIV>
<DIV><BR></DIV>I used to work for a computer OEM that indeed ordered 'custom'
drives with special SCSI commands built into the drives ROM but such things
are pretty rare nowadays because most OEM consumers wised up and pushed back.
The drive mfgrs don't really like this either anyway. I wouldn't
say it was impossible that this drive is a 'special' drive but it is unlikely.
I can't imagine that it would have to come from the Storagetek factory
with a special format. For SCSI that sort of thing (formatting) is
usually more in the domain of the controller chip on the bus controller card
(i.e., not on the interface chip of the drive like IDE drives). That was
one of the main tenets of IDE.<BR><BR>I'm just shooting from the hip here but
it would seem to me there has to be some utility/capability local on your
system to support what you want to do. Also, using the same model number
frive might be a *real* good idea but I am assuming you did that.
Whether Storagetek would ever want you to know how to do this might be
the real issue. Be sure and share the answer if you figure it
out.<BR><BR>Good luck.<BR><BR>Brandon Yu wrote:<BR>
