6. Complete the installation and reboot the server.
Note:
If the installation partitions are on a XP array, comment the following line in "defaults
section" in the /etc/multipath.conf file:
prio_callout "/bin/true"
If the installation partitions are on a MSA2xxxsa array, comment the following line in
"device section" of the MSA2xxxsa array in the /etc/multipath.conf file:
getuid_callout "/sbin/hp_scsi_id -g -u -n -s /block/%n"
Recommended configuration on SLES operating system
It is recommended to have a single path to the logical units while installing SLES10
operating systems and multiple paths to the logical units while installing SLES11 systems.
It is also recommended to mount the installation partitions using “by-label” fstab option.
If you are choosing to mount the installation partitions by device-id, ensure that you set the
"user_friendly_names" to "no" in /etc/multipath.conf file to avoid boot failures after
rebuilding the initrd image.
Note: For iSCSI SAN devices in SLES10SP2, use only “by-id” fstab option to mount the
installation partitions.
1. Start the installation of the operating system. For iSCSI SAN boot, complete the following
step, else go to Step 3
:
a. Provide the parameters “withiscsi=1 netsetup=1” to the kernel boot line for
SLES10SP2.
