How to install new hard drives on Sun Sparcstation 2+?

[Jauder Ho]

I just got two new SCSI drives and I am supposed to install
them. I have looked through the sun manuals and my sysadmin book but all
the info is really skimpy. So if anyone has any advice to offer or a FAQ
I could read I would really appreciate it. Thanks.

Jauder, I tried to reply by email, but it got returned. So here goes again:

I presume that you already have one drive up and running your system. Its SCSI
target number is probably 3, resulting in it being referred to as sd0. (I'm
going to use SunOS 4.1.3 parlance and directions, since it's what I have the most
experience with. If you are running Solaris or something else, you will have to
translate.)

Halt your system.

Cable together the new drives (I'm also assuming that they are external drives), hanging
them off any other peripherals you have (CDROM, Tape, etc.). Make sure the last
device in the chain has a SCSI terminator stuck into the extra connector. Order of
devices is unimportant.

There should be some sort of SCSI target selector on the back of each disk. Set them
to unused addresses. (Your old disk is 3, the CDROM is 6, the tape is 4, 7 is
reserved for the SCSI controller itself.) I recommend 1 and 2, if available. Make sure
the power switch is turned on for each one.

>From the ok monitor prompt, do a "probe-scsi" to see if all your SCSI devices show
up as planned. When all looks OK, reboot.

Go into format and set the partitions on your disks whichever way you want them. Use the "label" command to write the partition information to each disk. Exit from format.
(Note: you do not actually need to format the disks.)

For each partition that will have a filesystem on it (not the c partition), run the
"newfs" command.
newfs /dev/rsd1a (for example)
For good measure, run fsck on each partition, too.
fsck /dev/rsd1a

Create a directory entry to serve as a mount point for the new partitons. For example,
mkdir /files1/parta for partition a of sd1. You may wish to be more creative.

Edit the /etc/fstab file to add the partitions that you want mounted at boot time,
naming the mount point for each partition as defined in the previous step. Use
the existing lines in the file as an example, and/or read the man page for fstab.

Do "mount -a" to mount the new partitions. You're in business!

I am going on vacation tomorrow, so I won't be able to respond to any followup
questions after today. Hope this has steered you in the right direction, though.

Good Luck!
