Figure 1
Provided that all the LUNs are configured to be visible to the host through each HBA and each target
port, each LUN can be accessed by four different lunpaths corresponding to all the possible
combinations of HBAs and target ports. In HP-UX 11i v3, only one persistent DSF per LUN is exported
to applications. For instance, the following persistent DSFs exist:
• /dev/[r]disk/disk13
• /dev/[r]disk/disk14
• /dev/[r]disk/disk15
• /dev/[r]disk/disk16
