1. If you do not already have a directory called /SD_CDROM, type mkdir
/SD_CDROM to create a new directory.
2. Insert the compact disc into the CD-ROM drive.
3. Mount the drive as a file system.
a. Type: ioscan -fnkC disk
Look for the device name on the list with a name of the compact disc.
b. Type: mount /dev/dsk/c_t_d_ /SD_CDROM
Replace /dev/dsk/c_t_d_ with the device special file found in step 3.
4. Type: swinstall -s /SD_CDROM/hp-common
5. Restart your host system, then continue to step 6.
6. From the Software Selection window, click IBMis_tag.
7. From the Action menu, click Mark for Install.
8. When you see the word Yes next to the IBMis_tag product, go to the Action
menu and click Install.
9. When the analysis completes with no errors (Status- Ready), click OK.
10. Click Yes in the Confirmation window to begin the installation.
A window opens, notifying you that the installation is complete and that the
system needs to be restarted.
11. Click OK to continue.
12. Type swinstall -s var/spool/sw/ibm2105.
Configuring the ESS for clustering
This section describes how to configure a Hewlett-Packard host system for
clustering.
The steps to configure MC/ServiceGuard with the ESS are the same as the steps in
the Hewlett-Packard high-availability documentation. You can find that
documentation at the following Web site:
www.docs.hp.com/hpux/ha/index.html
After you configure your host for normal operating system access, the ESS acts as
a normal disk device in the MC/ServiceGuard configuration. IBM recommends that
you create volume groups that contain the volumes using the Hewlett-Packard
logical volume manager. This method of disk management is more reliable, easier,
and more flexible to manage than whole-disk management techniques.
Creating volume groups also allows you to implement PV-Links, Hewlett-Packard’s
built-in multipathing software, for highly available disks such as the ESS. To
establish PV-Links, perform the following steps:
1. Create the volume group, using the path to the volumes that you want as the
primary path to the data.
2. Extend the volume group with the path to the volumes that are intended as
alternate paths.
The logical volume manager reads the label on the disk and knows that it is an
alternate path to one of the volumes in the group. The logical volume manager
labels the volume.
For example, if a host has access to a volume on an ESS with the device
nodes c2t0d0 and c3t0d0, you can use the c2 path as the primary and create
the volume group using only the c2t0d0 path.
