Hi All,
Sorry to bother the list with trivial question, but the sun manuals
are absurdly opaque on this topic ("it happens automatically in the
default config, yay")
I've inherited management of a 4800 with a couple of direct-attached
6120 arrays (everything is out of support so I'm working with access
only to "free sunsolve", and no tech support from sun). One of the
arrays has a disk that went bad - not a problem since we're running
raid 5.
I've got a cold-spare part which is the identical part as the failed
drive (Seagate st373307fc, 73gig FCAL disk - although my cold spare is
a generic seagate part, NOT a sun part)
First question, I suppose, is - do I have any reason to this this
should work with a non-sun part? or will firmware of the disk make it
incompatible from the get-go? (hopefully not?!)
Second question, assuming I have any right to be doing this with a
generic disk:
When I remove the bad disk, and install the replacement part, the new
disk spins up fine (power LED on the new disk lights up persistently)
and I can see from the command-line-admin-interface that the device is
detected. However, it does not come online, nor does it rebuild the
raid.
A friendly kick in the right direction would be massively appreciated.
(i.e., what command syntax is expected to force the new disk to be
flagged as online and then permit rebuild of the raid volume?!)
Relavant output from command-line interface is shown below.
Many (!) thanks,
--Tim Chipman

(at this point, I had to remove and re-seat the u2d07 disk - the
"wrench amber LED" was lit for the disk. Removal and Replace resulted
in the amber light going away, the "blue ready for removal" LED
remains on, and the "green power is up" led also remains on).
