HP XC System Software Installation Guide Version 4.0

IMPORTANT: You must set the disk format to 8e to indicate that this is an LVM volume.
2. Create a physical volume and volume group. In the following example, VolGroup00 is the
name of the volume group. You are free to use any name you want to use.
# /usr/sbin/pvcreate /dev/sdb1
# /usr/sbin/vgcreate VolGroup00 /dev/sdb1
3. Build a logical volume on the volume group. The following example creates a 50 GB logical
volume named hptc_cluster_vol on volume group VolGroup00. HP recommends 50
GB as the size of the logical volume.
# /usr/sbin/lvcreate -L 50G -n hptc_cluster_vol VolGroup00
4. Create a file system on the logical volume:
# /sbin/mke2fs -m0 -j /dev/VolGroup00/hptc_cluster_vol
5. Create a new directory and mount the logical volume on it:
# /bin/mkdir -p /hptc_cluster
# /bin/mount -t ext3 /dev/VolGroup00/hptc_cluster_vol /hptc_cluster
6. Test the newly created /hptc_cluster file system. Verify that you can create a file on this
file system.
# df /hptc_cluster
# echo "Test of LVM" >> /hptc_cluster/LVM-test.txt
# cat /hptc_cluster/LVM-test.txt
7. Use a text editor to edit the /etc/fstab file and add the following entries to ensure that
the /hptc_cluster file system is always mounted when the node is rebooted.
/dev/VolGroup00/hptc_cluster_vol /hptc_cluster ext3 defaults 1 2
3.7 Changing MP Settings on Console Switches (Optional)
This task applies to CP3000 hardware configurations with HP Integrity servers and management
processors (MPs).
In order for the discovery process to work correctly using the MP in DHCP mode, you must
increase the amount of time the console switches hold MAC addresses from the default of 300
seconds to 1200 seconds.
Make this change only on the console switches in the system, typically the ProCurve 26xx series.
At the ProCurve prompt, enter the configuration mode and set the mac-age-time parameter,
as follows:
# config
(config)# mac-age-time 1200
3.8 You Are Done Preparing the System
You are done with system preparation tasks. Now, go to Chapter 4 (page 63) to discover the
hardware components.
