Identifying P-VOL and S-VOL LUs on Windows

In Navigator 2, the P-VOL and S-VOL are identified by their LU number. In
Windows 2003 Server, LUs are identified by HLUN. To map LUN to HLUN on
Windows, proceed as follows. These instructions provide procedures for
iSCSI and Fibre Channel interfaces.
1. Identify the HLUN of your Windows disk.
a. From the Windows Server 2003 Control Panel, select Computer
Management>Disk Administrator.
b. Right-click the disk whose HLUN you want to know, then select
Properties. The number displayed to the right of "LUN" in the dialog
window is the HLUN.
2. Identify HLUN-to-LUN Mapping for the iSCSI interface as follows. (If
using Fibre Channel, skip to Step 3.)
a. In the Navigator 2 GUI, select the desired array.
b. In the array tree that displays, click the Group icon, then click the
iSCSI Targets icon in the Groups tree.
c. On the iSCSI Target screen, select an iSCSI target.
d. On the target screen, select the Logical Units tab. Find the
identified HLUN. The LUN displays in the next column.
e. If the HLUN is not present on a target screen, on the iSCSI Target
screen, select another iSCSI target and repeat Step 2d.
3. Identify HLUN-to-LUN Mapping for the Fibre Channel interface, as
follows:
a. In Navigator 2, select the desired array.
b. In the array tree that displays, click the Groups icon, then click the
Host Groups icon in the Groups tree.
WARNING! Your host group changes will be applied to multiple ports. This
change will delete existing host group mappings and corresponding Host
Group IDs, corrupting or removing data associated with the host groups. To
keep specified host groups you do not want to remove, please cancel this
operation and make changes to only one host group at a time.
c. On the Host Groups screen, select a Host group.
d. On the host group screen, select the Logical Units tab. Find the
identified H-LUN. The LUN displays in the next column.
e. If the HLUN is not present on a host group target screen, on the Host
Groups screen, select another Host group and repeat Step 3d.
