HP 3PAR Solaris Implementation Guide

NOTE: If multiple paths to the LUNs have been used, the LUN appears as multiple instances

in the install program

8. Restart the Solaris interactive installation program.

NOTE: Continue the Solaris installation with appropriate responses, including selecting the

HP 3PAR StoreServ Storage LUN as an install target. A LUN will appear as multiple instances

if multiple paths have been used.

Select one instance for the Solaris OS installation. Configure the disk layout and confirm the

system warning of “CHANGING DEFAULT BOOT DEVICE” should it appear.

When the installation program completes, the server may not boot from the boot VLUN. If it

does not, check the SPARC PROM or the x86 BIOS settings for the HBA paths.

Configuring Additional Paths and Solaris I/O Multipathing

Optionally, a second path from the HP 3PAR StoreServ Storage to the Solaris host can be added

for path failure redundancy and load balancing using Solaris I/O Multipathing.

1. Connect an additional cable between the host server and the HP 3PAR StoreServ Storage

server.

2. Reboot the host server.

3. Add the new path to the host server’s host definition using the HP 3PAR OS createhost

command:

# createhost -add solaris-server 210100E08B275AB5

# showhost

Id Name ------WWN------- Port

1 solaris-server 210000E08B049BA2 0:5:2

210100E08B275AB5 1:5:2

If the HP 3PAR StoreServ Storage virtual volume was exported to the host definition, it will

now be exported on both paths to the host server:

# showvlun -a

Lun VVname Host ----Host_WWN---- Port Type

10 san-boot solaris-server 210000E08B049BA2 0:5:2 host

10 san-boot solaris-server 210100E08B275AB5 1:5:2 host

4. Verify that two representations of the boot volume now appear in the Solaris format command:

# devfsadm

# format
