HP Tru64 UNIX Technical Updates for the Version 5.1B and Higher Operating System and Patches (February 2010)

For example, assume the AdvFS domain uses disk dsk25c, which is a single hardware
RAID volume. To extend the capacity of the disk, create a concatset from it and another
single hardware RAID volume, as shown in the following example:

The following list explains each step:
6
Display the size of the
concatset C1.
4
Create a concatset
called C1 from
DISK10200.
1
Find unused disks —
those with an empty
(blank) Used by
field.
7
Note the size, as you
will need to modify
5
Add DISK20200 to
concatset C1 to create
a larger disk.
the disk label for
dsk25 on Tru64 UNIX
to match it.
2
DISK10200 (also
called D8) is used by
the AdvFS domain
that will be extended.
This storage volume
is recognized as
dsk25 on Tru64
UNIX.
3
DISK20200 is
unused.
2. Return to the Tru64 UNIX prompt.
3. Save a copy of the old disk label information for the volume:
# disklabel -r dskN > /tmp/label
For example:
# disklabel -r dsk25 > /tmp/dsk25MOD
4. Edit the saved label and increase the size of the partition used by AdvFS:
# vi /tmp/label
For example:
# vi /tmp/dsk25MOD
