VMS disks have no partitions. If You mean low level format, then You have to do it from the console firmware, depending on the system hardware.
But usually for SCSI one doesn't want to low level format, only creating the VMS on disk structure. And the utility/command is what You have in brackets: INITIALIZE.
Look at HELP INITIALIZE.

Hi Sir, the problem is I have recently added a new Seagate ST32430N HAWK 2.1SCSI drive to the system. it is low level formated and it is named as DKA0 on the system and it is Online. When I do "Initialize DKA0 Label-aaa" I receive "fatal drive error". The disk has no problem but I don't know how to Fdisk or Format the disk.

Please help

Even if You do a hard format (on another system), Your ancient VMS system 5.5 does not support this disk.
See e.g the topic
http://forums11.itrc.hp.com/service...

ion the VMS ITRC forum.
You have to upgrade to a newer VMS version, 6.2 or 7.3, then the disk might work.

One of the reasonsVMS doesn't like the disk, is the "write cache enable" bit and the " the read-write recovery flags" set in the drives firmware. If You have a system where You can run a SCSI utility to reset this bit, then do it and retry. Such a utility is included in newer VMS systems as sys$etc:scsi_mode.

I don't have the seagate model list ready accessible, but another reaon could be disk capacity restrictions on VMS 5.5 (4 or 9GB?), which also are relaxed at VMS 6 or 7.

Dear Joseph
Thanks a lot for your kind care.
The problem is I have a Seagate ST32430N RZ28M 2.1GB SCSI HDD installed on my OpenVMS5.5-2 system and it is working properly but when I install the same disk ST32430N but firmaware 0558 (not RZ28M) and start to initialize the disk, I receive "Fatal Drive Error" although the disk is online and has been recognized by the system as DKA200:. Also the disk installs under Alpha VMS easily.

Please let me know What I should do.

Yes, because it is VMS version 6.0 and higher, which supports the disks.
As I told You, also Vax VMS higher versions would work.
If You are not able to change the disks firmware, then You simply can't use it on Vax VMS 5.5, full stop.

Please reply.
With many thanks

You can't, and I can't, maybe the disk manufacturer can, but for a (old) 2GB disk it would be ridiculous to attempt.
I was a bit unclear in using the word 'firmware' in explaining to change some SCSI mode bits to make the disk acceptable for VMS 5.5.
There are changable pages containing some mode bits, which can be set/cleared by host computers.
I never did it myself, but I saved a conversation about the method:
get
http://wwwvms.mpp.mpg.de/vms$common...
to see what You can try, but I can't say at all if it works.
Other than that I have more ideas.

Just an additional pointer to the SCSI mode bits above: it is in the VMS FAQ:

And, if You can connect the system to a Linux or Windows system, the following utility may be of interest:
