Changes to setboot for Agile Addressing support

In agile addressing, setboot accepts persistent DSFs and lunpath hardware paths as valid input for

Primary, HA Alternate and Alternate boot paths.

Example:

Note: The following example is used across this section to illustrate the setboot behavior. In this example, the LUN

persistent DSF name is /dev/rdisk/disk13 and the LUN and lunpath hardware paths associated with

it are displayed by the ioscan command output below (trimmed to show only the LUN and lunpath entries for this

device):

Behavior of setboot on HP-UX 11i v3

1. When the persistent DSF of a LUN is given as input to set a boot path, setboot searches for an active lunpath

to that LUN, and writes it to stable storage as the boot path. This is the preferred method as setboot manages to

select a lunpath that is active and checks that it corresponds to a valid boot device.

NOTE: setboot may choose and write into stable storage any of the active lunpaths to the LUN.

Example: set the alternate boot path for the device with DSF disk13

# setboot –a /dev/rdisk/disk13

Alternate bootpath : 0/5/1/0.0x50001fe15001eead.0x4001000000000000 (/dev/rdisk/disk13)

2. If a user uses setboot to set up various boot paths (for instance, primary and alternate) using the same

persistent DSF name as input for each, setboot will try to use different lunpaths to the device with that

persistent DSF, provided there are several active lunpaths to the device.

Example: set the primary boot path for the device with DSF disk13 (in continuation of the example in 1. above)

# setboot –p /dev/rdisk/disk13

Primary bootpath: 0/5/1/0.0x50001fe15001eeac.0x4001000000000000 (/dev/rdisk/disk13)
