mkfs syntax after vxassist

Grew ufs volume (oraback) with vxassist:

vxassist -b growby 4g oraback

Need to run mkfs to extend volume (it is ufs); command needs number of sectors—is
that for the total number of sectors that volume would ultimately include
or the number of sectors that the volume should grow?

Do I find the number of sectors that I need to extend by in vxprint output
(length column) or is there a better way?

Assuming I figure out the number of sectors, is this the correct syntax?

mkfs -F ufs -M /oraback /dev/vx/rdsk/oracle/oraback 8388608

Finally, can this command be run with applications running, or should server
be in a quiescent state? Thanks in advance.

--yb

Volume lengths are given in 512 byte blocks.

To see the number of 512 byte blocks per sector on our filesystem, you
will need to do a "fstyp" on your filesystem. (or if your volume is on
disks with the same size, a prtvtoc on the disk(s)

The mkfs command can be run with applications running.
UFS is a monster in the sense that if there are some errors anywhere on
the filesystem, the mkfs 0m command will fail.

Now, remember for next time, do not use vxassist followed by mkfs, try
vxresize (works with gb or mb or blocks) which does both in 1 go.
