# lvreduce -m 0 /dev/vg00/lvolX /dev/dsk/c1t6d0

Of course, this can also be done automatically using a shell loop, e.g.:

# for lvol in lvol8 lvol7 ... lvol1(specify all LVs you need to reduce)

> do

> lvreduce -m 0 /dev/vg00/$lvol /dev/dsk/c1t6d0

> done

Root Mirror (Itanium based Systems)

The following procedure shows how to mirror the root disk. Let c3t2d0 be the existing

primary disk and c2t1d0 the new mirror boot disk:

1. Setup the disk partitions

A. Create a partition description file:

# vi /tmp/partitionfile

EFI 100MB

HPUX 100%

B. Use the idisk(1M) command to partition the disk according to this file:

# idisk -wf /tmp/partitionfile /dev/rdsk/c2t1d0

idisk version: 1.2

********************** WARNING ***********************

If you continue you may destroy all data on this disk.

Do you wish to continue(yes/no)? yes

...

2. Create the new device files for the new partitions (c2t1d0s1 and c2t1d0s2)

# insf -e -C disk

3. Use mkboot(1M) to format the EFI partition (s1), populate it with the EFI files

under /usr/lib/efi/, format the LIF volume (part of s2), and populate it with the LIF

files (ISL, AUTO, HPUX, LABEL) under /usr/lib/uxbootlf:

# mkboot -e -l /dev/rdsk/c2t1d0

# efi_ls -d /dev/rdsk/c2t1d0s1 (to check EFI)
