Presenting Eva Storage For Linux; Configuring Multipath With The Solaris 10 Iscsi Initiator; Mpxio Overview - HP StorageWorks 6100 - Enterprise Virtual Array User Manual

Linux does not unmount file systems that are being used by a process; therefore, any process using
those devices must be stopped (see the man page for fuser(1)) before iSCSI devices can be
unmounted.
To prevent file system corruption, the iSCSI shutdown script automatically stops all processes using
devices in /etc/fstab.iscsi. The script sends a SIGTERM signal to stop the processes, followed
by a SIGKILL signal to stop any remaining processes. It then 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 unmounted automatically.

Presenting EVA storage for Linux

To present EVA storage for Linux:
1. Set up the LUNs by using HP Command View EVA, as described in
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:
fdisk -l

Configuring multipath with the Solaris 10 iSCSI initiator

This section explains how to configure multipath with the Solaris 10 iSCSI initiator to the MPX200.

MPxIO overview

The Sun multipathing software (MPxIO) provides basic failover and load-balancing capability to HP
StorageWorks EVA4x00/6x00/8x00 storage arrays. MPxIO allows the merging of multiple SCSI
layer paths, such as an iSCSI device exposing the same LUN through several different iSCSI target
names. Because MPxIO is independent of transport, it can multipath a target that is visible on both
iSCSI and FC ports. This section describes only the iSCSI implementation of MPxIO with the MPX200.
For more information about MPxIO, see the Solaris Fibre Channel and Storage Multipathing
Administration Guide, available at http://docs.sun.com/source/819-0139.
Preparing the host system
To verify that MPxIO is enabled:
1. Enter the following command:
cat kernel/drv/iscsi.conf
2. Verify the MPxIO setting:
mpxio-disable="no"
If the setting is yes, change it to no, and then reboot:
Reboot -- -r
