Maintenance mode booting

I am new to hp unix,can any one tell the difference between single user mode and maintenance mode and when this mode will be helpful in practical situations other than changing the password

Thanks in advance

Re: Maintenance mode booting

Hi,

* In maintance mode vg00 will not activate instead root will mount with auxiliary device file.
* In single usermode only /stand and / will mount.

Besides changing passwords, u can recover and repairing file systems, make root backups, configuring kernel etc.

hpux -is => boot to single-user mode

hpux -lm => Boot the system in LVM maintenance mode, configure only the root volume, and then initiate single user mode.

lm is used for LVM maintenance mode.

Re: Maintenance mode booting

I think u meant LVM maintenance mode by maintenance mode.. LVM maintenance mode is used to reapir LVM structure ie vg related commands can be executed in this mode after mounting the corresponding filesystems. If BDRA etc is corrupt then u won't be able to boot in single user or any other mode except LVM maintenance mode since this uses the LABEL to boot.

single user mode is quite similar to other unix flavours and could be used to repair non-root filesystems etc, obviously there are many task which can be performed in single user mode but that depends.
