(iSCSI) LVM devices are not automatically mounted during system boot on SUSE Linux Enterprise Server 10
Currently, the volume groups created on iSCSI devices are not automatically scanned when iSCSI LUNs are discovered. Therefore, during the system boot, the volume groups that were created on the iSCSI devices are unavailable. To overcome this problem, a helper script is provided in /usr/share/doc/packages/lvm2/ lvm-vg-to-udev-rules.sh.
(iSCSI) Poor performance due to misalignment of partitioned LUNs
If you experience poor performance on some or all LUNs that have partitions, the alignment between the LUN block boundaries and the underlying WAFL boundaries might not match. Manually enter the disk geometry parameters when creating partitions with the fdisk command.
iSCSI: LUNs not visible on the Linux host
iSCSI LUNs appear as local disks to the host. If the storage system LUNs are not available as disks on the hosts, verify the configuration settings.
