Only in that adding all three up and multiplying by 1024 gives 4.1gb, adding 200mb for swap would suggest a 4.3gb disk drive. If there are two drives they are probably mirrored.

When the system boots, before the "boot:" prompt, you should see the following:
1 the amount of memory available.
2 a "<ctrl>A" prompt for the Adaptec host adapter.
3 a line For each SCSI device attached.
4 a "<ctrl>M prompt for the Mylex host adapter.
5 a list of System Disks and their state.
State will be either online, degraded, dead or offline
If there is only one system disk then u1 was always on the same drive as root.
If there is more than one system disk, and it is not online or degraded, then you have to determine why it is dead or offline, and resolve this.
You can rebuild a degraded system disk, or make an offline system disk online, by typing <ctrl>M and running the menu driven RAID configuration software.
If the system disk is dead, it means that enough drives of the cluster have failed to make recovery of the data impossible (eg both drives of RAID1 or more than 1 drive of a RAID5 configuration.)
Offline means that the disk is unavailable for use, marking it online is an option of the configuration software.
You should also have about 5 diskettes and several manuals for the Mylex controller.
There is also a command line version of this software with limited capabilities that you can run while the system is up.
/etc/dac960sh
and
/etc/dac960tk

There are man pages for both.
