files can create incompatibilities during the boot process

For this reason, this part of the process is being skipped.

The only operation that should be performed when the

client is not installed with at least 11.00, is rebuilding

Filesystem kbytes used avail %cap iused ifree iused Mounted on

/ROOT 163840 70173 87840 44% 2486 23414 10% ?

Filesystem kbytes used avail %cap iused ifree iused Mounted on

/ROOT/stand 128232 74047 41361 64% 65 20415 0% ?

b. Return to the HP-UX Recovery Media Main Menu.

Selection:

Once you find yourself at the Recovery Completion menu, complete the recovery process

by selecting a, reboot the target system. This completes the process for replacing the

kernel only.

Co-Procedure: Booting to Single User and LVM Maintenance Mode

In the following section, we show only the user interface that newer systems like N- or L-Class

offer. If your system displays different messages during bootup you may find appropriate

information in the section Different Boot Modes for Different Machine Types.

1. During the system’s boot sequence it will usually wait and display the following or

similar messages if Autoboot is enabled:
