HP StorageWorks SAN Virtualization Services Platform administrator guide (5697-0204, January 2010)

1. From the VSM GUI:
a. Verify that you can see the LUN presented by the storage array as back-end LUs.
b. Follow the HP StorageWorks SAN Virtualization Services Platform Manager user guide
procedures to create a storage pool.
c. Follow the HP StorageWorks SAN Virtualization Services Platform Manager user guide
procedures to create a virtual disk from the storage pool.
d. Follow the HP StorageWorks SAN Virtualization Services Platform Manager user guide
procedures to configure a UDH for the VMware server (choose VMware for the OS type,
and the HP EVA personality for the SCSI personality type).
e. Assign the VSM virtual disk only to the ESX server that will use the virtual disk as its boot
device.
2. Follow VMware instructions on how to configure the HBAs. See Chapter 5 in the VMware Fibre
Channel SAN Configuration Guide for ESX Server 3.5 that can be obtained at http://
www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_san_cfg.pdf, or for ESX 4.0 that
can be obtained at http://www.vmware.com/pdf/vsphere4/r40/vsp_40_san_cfg.pdf. Make
sure to apply these instructions to all HBAs and HBA ports for HA.
3. Insert the ESX install CD into the server and reboot the server.
4. While the server is rebooting, at the BIOS level, verify the SVSP virtual disk was recognized by
the HBA BIOS.
5. In the ESX install wizard, verify that the installation will be done to the VSM virtual disk. You are
able to recognize the VSM virtual disks because they have HP in their names.
