Hello,


I currently have a ds20 with 4.0F installed out of the box. There are three raid arrays
attached to it that look like this:

SWXCR xcr0 logical drive parameters:

RAID Array 200 Controller Family Information Utility V1.03
Copyright (c)1997,1998 by Compaq Computer Corporation, all rights reserved.




***** Logical Drive Information for xcr0 *****

Drive groups on this controller:
--------------------------------
   Group 0 : <1,0><1,1>
   Group 1 : <1,2><1,3><2,0>
   Group 2 : <2,1><2,2>

 Logical drives configured:
---------------------------
   Logical Drive
   Drive RAID Size Cache Group Current
   Number: Level: (in MB): Policy: Spanned: Status:
   ---------------------------------------------------------
     0 1 8678 WRITE THRU 0 OPTIMAL
     1 5 17356 WRITE THRU 1 OPTIMAL
     2 1 8678 WRITE THRU 2 OPTIMAL



The OS is installed on a part of re0 like this:
prssql> df
Filesystem 512-blocks Used Available Capacity Mounted on
/dev/re0a 258142 110474 121852 48% /
/proc 0 0 0 100% /proc
/dev/re0g 1411742 432856 837710 35% /usr

I need to setup the rest of re0, and both re1 and re2. I am from the BSD world (pardon me :) )

so I would do this to add prepare the disks, disklabel, and newfs them in BSD:




    # dd if=/dev/zero of=/dev/rre1 bs=1k count=1
    # disklabel -Brw re1 auto
    # disklabel -e re1 # create the `e' partition
    # newfs -d0 /dev/rre1e
    
And so forth. Of course, there is already a disklabel for re0 but there is none for re[1,2].


I have worked on tru64 before but I just want to be sure I am doing this right and the above procedure
would work. Would the above work in tru64? Thanks for your time. I will summarize for those
interested.
