Hi,

Is the replacement of the two 72GB drives w/ two 146GB drives just
because you can get the drives quicker for replacement?

Because you dont use the additional added space from the step to 146GB drives, I can write a little how-to of doing that if you want..

In short :

-) Break the 2x72GB mirror by removing the second disk (c0t1d0)
-) Remove the drive and insert a 146GB drive
-) Copy (for now) the VTOC from disk1 (72GB) to disk2 (146GB) OR
create the needed existing partitions by hand and create a big (or two/three..) slice/partition to hold the additional ~65GB space
-) Create metadb replicas on the 146GB disk
-) Start mirror sync
-) When mirrored, break the mirror and remove the first (72GB) disk, V240 now runs from the 146GB disk in slot 2
-) Insert the other 146GB disk and copy the VTOC from disk2 like stated from j�rg via prtvtoc , I always add the additional '-sh' arg to prtvtoc
prtvtoc -sh | fmthard -s -
-sh removes the human readable index and stuff , MAN page states that those arguments should be used when duplicating the VTOC from disk to disk
-) Create metaDBs on disk1 and mirror the disk
-) Create a filesystem on the new slice to use the additional space (of course on the metadevice)
-) D O N E

greets,
Christopher

vxbootsetup

vxbootsetup(1M) 														   vxbootsetup(1M)

NAME

       vxbootsetup - set up system boot information on a Veritas Volume Manager disk

SYNOPSIS

       /etc/vx/bin/vxbootsetup [-g diskgroup] [medianame ... ]

DESCRIPTION

       The  vxbootsetup utility configures physical disks so that they can be used to boot the system. Before vxbootsetup is called to configure a
       disk, the required volumes, standvol, rootvol and swapvol (and optionally, dumpvol) must be created on the disk.  All of these volumes must
       be contiguous with only one subdisk.

       The -g option may be used to specify the boot disk group.

       If  no  medianame arguments are specified, all disks that contain usable mirrors of the root, swap, /usr and /var volumes are configured to
       be bootable.

       If medianame arguments are given, only the disks that are associated with the specified disk names are configured to be bootable.

       vxbootsetup requires that:

       o    The root volume must be named rootvol and must have a usage type of root.

       o    The swap volume must be named swapvol and must have a usage type of swap.

       o    The volumes containing /usr and /var (if any) must be named usr and var, respectively.

       See the chapter "Recovery from Boot Disk Failure" in the Veritas Volume Manager Troubleshooting Guide for detailed information on  how  the
       system boots and how VxVM impacts the system boot process.  The vxmirror, vxrootmir, and vxresize utilities call vxbootsetup automatically.
       If you use vxassist, or vxmake and vxplex to create mirrors of the root volume on a disk, you must run vxbootsetup explicitly to  make  the
       disk bootable.

ARGUMENTS

       medianame
	    Specifies the disk name (disk media name) of a VM disk that is to be configured as bootable.
