HP 3PAR SUSE Linux Enterprise Implementation Guide

Important
• During the installation, make sure only a single HP 3PAR StoreServ Storage VLUN is exported
to the host and leave all other HP 3PAR StoreServ Storage VLUNs not exported until the SUSE
installation is complete.
• Mount the devices by using the /dev/disk/by-id path.
• Check by-id information is used in the /etc/fstab and /boot/grub/menu.lst.
• Rebuild the ramdisk by running /sbin/mkinitrd -f <option> to update the initrd
image.
NOTE: See the SLES 11 Deployment Guide, which is available on the following website:
SUSE
1. When starting the installation, at the Linux Menu installation prompt press Enter and follow
the normal installation procedure when installing from the CD/DVD.
2. When the installation completes, make sure that the multipathing tools are installed (use rpm
-qa | grep multipath). If these tools are not installed, install them from the installation
CD/DVD.
3. Verify that the HP 3PAR StoreServ Storage can see all the ports from the host using the
showhost command.
4. From the server, perform an fdisk -l and verify that the server can see the boot partition
from the multiple device paths.
# fdisk -l

5. Obtain the scsi_id using the scsi_id command for each device instance.
# scsi_id -g -u -s /block/sda
350002AC00003011B
# scsi_id -g -u -s /block/sdb
350002AC00003011B
6. Verify that the scsi_ids are the same for each device instance.
