Ignite-UX and MirrorDisk/UX
the block disk device of the alternate boot disk. This is to ensure that when software is installed
the contents of the boot LIF both disks are updated.
# cat /stand/bootconf
l /dev/dsk/<boot disk>
After creating an alternate boot disk using LVM, HP recommends you test that it can boot and
operates as expected.
How to mirror the root disk on an HP Integrity Server
1.
Determine the how the current boot disk is currently partitioned. You must make the EFI and
HPSP
2
partitions the same size as on the current boot disk. You can determine the size of the
different partitions using the following commands:
# diskinfo -b /dev/rdsk/<boot disk>s1 | awk '{print $1 / (1024)}'
# diskinfo -b /dev/rdsk/<boot disk>s2 | awk '{print $1 / (1024)}'
# diskinfo -b /dev/rdsk/<boot disk>s3 | awk '{print $1 / (1024)}
2.
The three commands in the previous step show the size in Megabytes of the EFI partition (section
1), the HP-UX partition (section 2), and the HPSP partition (section 3). Place those values into the
following command:
# print '3\nEFI 500MB\nHPUX *****MB\nHPSP 400MB' > /tmp/partitionfile
Or you can choose to create the /tmp/partitionfile file using vi when performing this
interactively.
Note:
If you do not have a HPSP partition, the initial 3
in the command should be 2 and the command would
instead look like:
# print '2\nEFI 500MB\nHPUX *****MB\n' > \
/tmp/partitionfile
If the boot disk and the alternate boot disk are different sizes, and you do not wish to calculate
the size of the HP-UX partition, you could execute the print command as follows:
# print '3\nEFI 500MB\nHPUX 100%\nHPSP 400MB' > /tmp/partitionfile
This creates the EFI and HPSP partitions at a fixed size and allocates 100% of the remaining
space to the HP-UX partition.
3. The alternate boot disk must be partitioned using the file /tmp/partitionfile created in the
previous step. This action is performed using the idisk command and echo yes is used to
2
This is the HP Service Partition. You should always let this partition be created when installing an HP Integrity server, as it holds the offline
diagnostics for HP Integrity systems.
