Mirroring a Boot Disk with LVM on HP-UX 11i for HP Integrity<\/p>\n

Servers<\/p>\n

The following diagram shows the disk layout of a boot disk. The disk<\/p>\n

contains a Master Boot Record (MBR) and Extensible Firmware<\/p>\n

Interface (EFI) partition tables that point to each of the partitions. The<\/p>\n

idisk<\/strong><\/p>\n

command is used to create the partitions (see idisk <\/em>(1M)).<\/em><\/em><\/p>\n

Figure 6-5 Example LVM Disk Layout on HP Integrity Server<\/em><\/p>\n

Before starting the procedure, make sure that add-on product HP<\/em><\/p>\n

MirrorDisk\/UX (B5403BA) is installed. This product is an extra-cost<\/em><\/p>\n

product available on the HP-UX 11i application release media. For<\/em><\/p>\n

example:<\/em><\/p>\n

swlist -l fileset | grep -i mirror<\/em><\/strong><\/em><\/p>\n

LVM.LVM-MIRROR-RUN B.11.22 LVM Mirror<\/em><\/p>\n

Step 1.<\/em><\/p>\n

file.<\/em><\/p>\n

Partition the disk using the <\/em>idisk <\/em>command and a partition description<\/em><\/em><\/p>\n

a.<\/em><\/p>\n

Create a partition description file. For example:<\/em><\/em><\/p>\n

vi \/tmp\/idf<\/em><\/strong><\/em><\/p>\n

In this example the partition description file contains:<\/em><\/p>\n

3<\/em><\/p>\n

EFI 500MB<\/em><\/p>\n

HPUX 100%<\/em><\/p>\n

HPSP 400MB<\/em><\/p>\n

NOTE<\/em><\/p>\n

an EFI partition, an HP-UX partition, and an HP Service partition.<\/em><\/p>\n

Boot disks of earlier HP Integrity Servers may have an EFI partition<\/em><\/p>\n

of only 100MB and may not contain the HPSP partition.<\/em><\/p>\n

The values in the example represent a boot disk with three partitions:<\/em><\/em><\/p>\n

b.<\/em><\/p>\n

Partition the disk using <\/em>idisk <\/em>and your partition description file:<\/em><\/em><\/p>\n

idisk -f \/tmp\/idf -w \/dev\/rdsk\/c3t1d0<\/em><\/strong><\/em><\/p>\n

c.<\/em><\/p>\n

To verify you can run:<\/em><\/em><\/p>\n

idisk \/dev\/rdsk\/c3t1d0<\/em><\/strong><\/em><\/p>\n

Step 2.<\/em><\/p>\n

the partitions. For example:<\/em><\/p>\n

Use the <\/em>insf <\/em>command with the <\/em>-e <\/em>option to create the device files for all<\/em><\/em><\/p>\n

insf -e -H 0\/18\/1\/2\/0.0.1.0<\/em><\/strong><\/em><\/p>\n

You should now have eight device files for this disk:<\/em><\/p>\n

\/dev\/[r]dsk\/c?t?d?<\/em><\/p>\n

(This refers to the entire disk)<\/em><\/p>\n

\/dev\/[r]dsk\/c?t?d?s1<\/em><\/p>\n

(This refers to the EFI partition)<\/em><\/p>\n

\/dev\/[r]dsk\/c?t?d?s2<\/em><\/p>\n

(This will be the HP-UX partition)<\/em><\/p>\n

\/dev\/[r]dsk\/c?t?d?s3<\/em><\/p>\n

(This refers to the Service partition)<\/em><\/p>\n

Step 3.<\/em><\/p>\n

disk:<\/em><\/p>\n

Use <\/em>pvcreate <\/em>to make the HP-UX partition of the disk an LVMmanaged<\/em><\/em><\/p>\n

pvcreate -B \/dev\/rdsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

Step 4.<\/em><\/p>\n

Add the disk to <\/em>vg00<\/em>:<\/em><\/em><\/p>\n

vgextend vg00 \/dev\/dsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

Step 5.<\/em><\/p>\n

Place the boot files on the disk using <\/em>mkboot<\/em>:<\/em><\/em><\/p>\n

mkboot -e -l \/dev\/rdsk\/c3t1d0<\/em><\/strong><\/em><\/p>\n

Step 6.<\/em><\/p>\n

Copy any autoboot file from the original boot disk to this one.<\/em><\/em><\/p>\n

a.<\/em><\/p>\n

partition to the current directory. Make sure to use the device file<\/em><\/p>\n

with the<\/em><\/p>\n

Use <\/em>efi_cp <\/em>to copy the <\/em>AUTO <\/em>file from the original boot disk\u2019s EFI<\/em>s1 <\/em>suffix, as it refers to the EFI partition:<\/em><\/em><\/p>\n

efi_cp -d \/dev\/rdsk\/cntndns1 -u \/efi\/hpux\/auto .\/AUTO<\/em><\/strong><\/em><\/p>\n

b.<\/em><\/p>\n

partition:<\/em><\/p>\n

Copy the file from the current directory into the new disk\u2019s EFI<\/em><\/em><\/p>\n

efi_cp -d \/dev\/rdsk\/c3t1d0s1 .\/AUTO \/efi\/hpux\/auto<\/em><\/strong><\/em><\/p>\n

Step 7.<\/em><\/p>\n

volume group onto the desired physical volume. The logical volumes<\/em><\/p>\n

must be extended in the same order that they are configured on the<\/em><\/p>\n

original boot disk. Use the<\/em><\/p>\n

determine the list of logical volumes and their order. For example:<\/em><\/p>\n

Use the <\/em>lvextend <\/em>command to mirror each logical volume in the root<\/em>pvdisplay <\/em>command with the <\/em>-v <\/em>option to<\/em><\/em><\/p>\n

pvdisplay -v \/dev\/dsk\/c0t0d0s2 | grep \u2019current.*0000$\u2019<\/em><\/strong><\/em><\/p>\n

00000 current \/dev\/vg00\/lvol1 00000<\/em><\/p>\n

00038 current \/dev\/vg00\/lvol2 00000<\/em><\/p>\n

00550 current \/dev\/vg00\/lvol3 00000<\/em><\/p>\n

00583 current \/dev\/vg00\/lvol4 00000<\/em><\/p>\n

00608 current \/dev\/vg00\/lvol5 00000<\/em><\/p>\n

00611 current \/dev\/vg00\/lvol6 00000<\/em><\/p>\n

00923 current \/dev\/vg00\/lvol7 00000<\/em><\/p>\n

01252 current \/dev\/vg00\/lvol8 00000<\/em><\/p>\n

In this example, mirror the logical volumes as follows:<\/em><\/p>\n

lvextend -m 1 \/dev\/vg00\/lvol1 \/dev\/dsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

lvextend -m 1 \/dev\/vg00\/lvol2 \/dev\/dsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

lvextend -m 1 \/dev\/vg00\/lvol3 \/dev\/dsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

lvextend -m 1 \/dev\/vg00\/lv0l4 \/dev\/dsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

lvextend -m 1 \/dev\/vg00\/lvol5 \/dev\/dsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

lvextend -m 1 \/dev\/vg00\/lvol6 \/dev\/dsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

lvextend -m 1 \/dev\/vg00\/lvol7 \/dev\/dsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

lvextend -m 1 \/dev\/vg00\/lvol8 \/dev\/dsk\/c3t1d0s2<\/em><\/strong><\/em><\/p>\n

If<\/em><\/p>\n

lvextend <\/em>fails with following message:<\/em><\/em><\/p>\n

“m”: Illegal option<\/em><\/p>\n

then HP MirrorDisk\/UX is not installed.<\/em><\/p>\n

Step 8.<\/em><\/p>\n

Update the root volume group information:<\/em><\/em><\/p>\n

lvlnboot -R \/dev\/vg00<\/em><\/strong><\/em><\/p>\n

Step 9.<\/em><\/p>\n

disk and that the boot, root, and swap logical volumes appear to be on<\/em><\/p>\n

both disks:<\/em><\/p>\n

Display the BDRA. Verify that the mirrored disk is displayed as a boot<\/em><\/em><\/p>\n

lvlnboot \u2013v<\/em><\/strong><\/em><\/p>\n

Step 10.<\/em><\/p>\n

Specify the mirror disk as the alternate boot path in nonvolatile memory:<\/em><\/em><\/p>\n

setboot -a path_to_disk<\/em><\/strong><\/em><\/p>\n

Step 11.<\/em><\/p>\n

text editor:<\/em><\/p>\n

Add a line to <\/em>\/stand\/bootconf <\/em>for the new boot disk using <\/em>vi <\/em>or another<\/em><\/em><\/p>\n

vi \/stand\/bootconf<\/em><\/p>\n
