HP 3000 Enterprise Virtual Array - Manual (Page 85)

To avoid file system corruption, the iSCSI shutdown script automatically stops all processes using
devices in /etc/fstab.iscsi, first by sending them SIGTERM, and then by sending any remaining
processes SIGKILL. The iSCSI shutdown script unmounts all iSCSI file systems and stops the iSCSI
daemon, terminating all connections to iSCSI devices.
CAUTION:
File systems not listed in /etc/fstab.iscsi cannot be automatically unmounted.
Presenting EVA storage for Linux
To set up LUNs using HP Command View:
1. Set up LUNs using HP Command View. For procedure steps, see “ Using HP Command View EVA
to configure LUNs to iSCSI initiators ” on page 127.
2. Set up the iSCSI drive on the iSCSI Initiator:
a. Restart the iSCSI services:
/etc/rc.d/initd/iscsi restart
b. Verify that the iSCSI LUNs are presented to the operating system by entering the following
command:
fdisk -l
iSCSI Initiator setup for Solaris (single-path)
The Solaris iSCSI driver is included in the Solaris 10 operating system with the following software
packages:
• SUNWiscsir–Sun iSCSI Device Driver (root)
• SUNWiscsiu–Sun iSCSI Management Utilities (usr)
EVA LUN 0 with Solaris iSCSI Initiators
By default, LUN 0 is assigned to an iSCSI Initiator when the initiator logs in to the mpx100b iSCSI
target and when HP Command View EVA presents a virtual disk to an iSCSI host.
Because the Solaris iSCSI Initiator does not recognize LUN 0 as the EVA controller console LUN, the
initiator tries to bring LUN 0 online, resulting in the following warning:
Mar 21 08:04:09 hdxs8j iscsi: [ID 248668 kern.warning] WARNING: iscsi
driver unable to online iqn.1986–03.com.hp:fcgw.mpx100:hdxh05–m2.0.50001
fe1500aef60.50001aef68 LUN 0
LUN 0 can be prevented from being sent to the Solaris iSCSI Initiator by disabling the Controller LUN
AutoMap parameter with the mpx system settings.
LUN 0 is not presented to any host entry in HP Command View 8.0 with any iSCSI host mode setting
of Solaris.
