6. Refresh the SANsurfer GUI and change the target ID of one target (for example, change it to 3).
Observe that the rest of the targets are grayed out.
7. Create a new initrd image using mkinitrd <initrd image path> <kernel_version>.
8. Edit the file /boot/grub/menu.lst to boot with the new initrd image and reboot. During the
reboot, observe that the new target ID is used for all the LUNs. This can be verified when we
display all the LUNs using lssd. On subsequent reboots the device IDs should not change.
OpenVMS multipathing
Not available at the time of publication.
Solaris 9 multipathing
This procedure configures a Solaris 9 server for use with SVSP:
1. Enable MPxIO:
a. Install the StorEdge Foundation Suite (use the install_it script).
b. Edit the /kernel/drv/scsi_vhci.conf file and change mpxio-disable=”no” to
mpxio-disable=”yes”.
c. Perform a configuration reboot.
2. Disable AutoFailback:
a. Open the /kernel/drv/scsi_vhci.conf file in a text editor.
b. Disable the automatic failback capability by changing the auto-failback entry to:
auto-failback="disable";
c. Save and exit the file.
d. Reboot the system with the # shutdown -g0 -y -i6 command.
3. Verify the system is working:
# cfgadm –al
# devfsadm –Cv
# format (to see all the volumes mapped)
4. Make sure you are using the correct HBA driver.
Solaris 10 multipathing
This procedure configures a Solaris 10 server for use with SVSP:
1. Enable MPxIO:
a. The MPxIO driver is installed and disabled by default on Solaris 10 SPARC servers for Fibre
Channel devices. To enable MPxIO, type # stmsboot –e. A reboot is required.
b. The MPxIO driver is installed and enabled by default in Solaris 10 x86–based servers. To
verify, open /kernel/drv/fp.conf and check for the line: mpxio-disable=”no”;.
If it is not enabled, then change “no” to “yes.” Perform a reconfiguration reboot:
# touch /reconfigure
# shutdown -g0 -y -i6
