HP 3PAR RedHat and Oracle Linux Implementation Guide

4. Check the block device files created in the system:
# ls /sys/block/sd*
/sys/block/sda:
dev device queue range removable sda1 size stat
5. Verify which block device files are HP 3PAR volumes:
# cat /sys/block/sd*/device/vendor
ATA
ATA
3PARdata
6. You can verify an iSCSI device with the following command:
# iscsi-device /dev/sdc
/dev/sdc is an iSCSI device
WARNING! The current RHEL 4 Update 5 iSCSI implementation does not properly handle
the mounting of file systems on iSCSI devices bootup time and does NOT properly handle the
unmounting of file systems on iSCSI devices while shutting down and/or rebooting the host.
A workaround is to have scripts to mount the file systems after the host has booted and the
proper devices have been created and have scripts to unmount them before shutting down or
rebooting the host.
