This menu must be used to verify the system's boot string.

When the information is correct, select 'a'.

INFORMATION to verify:

The system's boot string should be:

'hpux -lm /stand/vmunix'

NOTE: The Boot address is {0/0/2/0.0.0}

the Root address is {0/0/1/0.1.0}.

Select one of the following:

a. The above information is correct.

b. WRONG!! Prompt the user for the system's boot string.

m. Return to the 'HP-UX Recovery MENU.'

x. Exit to the shell.

NOTE: For an LVM '/'(ROOT) the '-lm' option MUST be specified

(example: 'hpux -lm /stand/vmunix' )

Selection:

6. Confirm the boot string entering a, otherwise correct it after entering b. The following or

similar messages are displayed next:

*********** Installing bootlif ***********

mkboot -a hpux -lm /stand/vmunix /dev/rdsk/c2t0d0

After bringing the system back online the SWAP, BOOT and DUMP

volume information in the BOOTLIF should be restored.

For example:

BOOT:

If '/stand' is on a separate logical volume, then use

lvlnboot -b /dev/<rootvg>/<lv of '/stand'> .

Otherwise BOOT and ROOT are considered identical.

DUMP:

lvlnboot -d /dev/<rootvg>/<lv0 of dump>

lvlnboot -d /dev/<rootvg>/<lv2 of dump>

SWAP:

lvlnboot -s /dev/<rootvg>/<lv0 of swap>

Refer to the lvlnboot man page for more information.

FILE SYSTEM CHECK

The file system check '/sbin/fs/hfs/fsck -y /dev/rdsk/c2t0d0s1lvm'

will now be run.

Select one of the following:

a. Run fsck -y .

b. Prompt for the fsck run string on c2t0d0s1lvm.

m. Return to the 'HP-UX Recovery MENU.'

7. Select a to run fsck -y to check your file system for corruption; you will see a display

similar to the following:

** /dev/rdsk/c2t0d0s1lvm

** Last Mounted on /ROOT/stand

** Phase 1 - Check Blocks and Sizes
