I believe it's a SCSI disk with an SCA connector. That's a special connector for SCSI drives that are hot swappable. A single connector on the back of the drive carries data, control, and power to the drive.
If the system runs, do the following command...
This will give you something like...
Code:
Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c0t0d0s1 2569479 2115488 402602 85% /
The first part is the logical device name. That's the [tt]/dev/dsk/c0t0d0s1[/tt] part. The "[tt]c0t0d0s1[/tt]" means; Controller 0 (c0), Target 0 (t0), Disk 0 (d0), Slice 1 (s1). If there's a "Target", it's SCSI. If it's IDE, it would look like [tt]/dev/dsk/c0d0s1[/tt].
You can also confirm this by doing this...
This gives you something like...
Code:
lrwxrwxrwx 1 root root 51 May 20 16:25 /dev/dsk/c0t0d0s1 -> ../..
/devices/sbus@1f,0/SUNW,fas@e,8800000/sd@0,0:b
This gets you the physical device name. That [tt]sd[/tt] toward the end means it's a SCSI disk.
The [tt]sbus@1f,0[/tt] is the internal SBUS. The [tt]SUNW,fas@e,8800000[/tt] is a SCSI controller on that bus. The [tt]sd@0,0:b[/tt] is the SCSI Disk 0 at target 0, slice 1 ([tt]:b[/tt]).
You can also use the [tt]format[/tt] command to check the drives.
You can also go to Sun's documentation and check the specs. Go to
for the Sparc 5 and 10.
Finally you can open up the case and see what it is! You may have to check the model number and Google it or go to the vendor's web site.
Hope this helps.
