Re: server booting error

Have you looked for errors in /etc/rc.log as it suggested?

Any tools in /sbin that can display it?  cat?

It looks like /usr isn't mounted.  Is /etc/fstab corrupt?

Re: server booting error

Please run:

# cat /etc/fstab

 

If you're using a terminal emulator that has a scroll-back buffer, you might also run:

# cat /etc/rc.log

 

The /sbin directory should not be a separate filesystem: it should be just a directory on the root filesystem, because it contains /sbin/mount which is used to mount all the other filesystems.

 

The error messages you posted are symptoms of an earlier error in mounting the /usr filesystem. If /usr is not mounted, basic commands like /usr/bin/ps and /usr/bin/grep are not available.

 

The normal error message when trying to mount /sbin would have been:

# mount /sbin
mount: /sbin was either ignored or not found in /etc/fstab

 But your system said "mount: file system table may be corrupt". /etc/fstab is the file system table.

 

As a temporary work-around until /etc/fstab is fixed, you can mount the LVs of vg00 manually. If your HP-UX installation uses the default layout for vg00, these commands should do it:

# mount -o rw,remount /dev/vg00/lvol3 /
# mount /dev/vg00/lvol1 /stand
# mount /dev/vg00/lvol4 /tmp
# mount /dev/vg00/lvol5 /home
# mount /dev/vg00/lvol6 /opt
# mount /dev/vg00/lvol7 /usr
# mount /dev/vg00/lvol8 /var

 

When you specify both the device and the mountpoint, the mount command is independent of /etc/fstab. But if one of those (or both, as in case of "mountall" or "mount -a") is omitted, the command will look up the missing information from /etc/fstab. But in your case, /etc/fstab seems to be corrupted (or perhaps missing?), so the look-up will not work.

Re: server booting error

i was run the

# cat /etc/fstab

 

it show nothing output. so i understand fstab file corrupt ,am i right Matti

 

next setp, previously i have taken fstab backup in my system, so in single user mode i mount all mount points that you mentioned , then i user vi fstab and upend my entries, once done i reboot the server. but now i face attached error, it is booting again and again.

 

pls advise

Definitely, yes.

 

Your current error messages indicate there is still something wrong with your restored /etc/fstab:

mount: ignoring incomplete/incorrect entry for System in /etc/fstab
mount: ignoring incomplete/incorrect entry for See in /etc/fstab


Apparently, you have one line in /etc/fstab with the word "System" on it, and another with the word "See" on it. These lines are not in the correct format. Could you please boot the system to single user mode again and show your current /etc/fstab?


But the reason your system is rebooting is that another important file seems to be corrupted too:

$X@: ioinit: Rebooting the system because /etc/ioconfig and /stand/ioconfig files are inconsistent

 

Normally, the system automatically keeps /etc/ioconfig and /stand/ioconfig in sync with each other. Based on the fact that we already know /etc/fstab was corrupted, I assume that /etc/ioconfig is corrupted too.

 

(I worry about the "$X@" in the beginning. I would have expected something like the server hostname in its place. Maybe there are still more corrupted files in your /etc?)


If you cannot find a valid copy of /etc/ioconfig from your backups, you might want to completely recreate the ioconfig files from scratch. This will cause the system to forget all device instance numbers and relabel them from scratch, so it's better if you can restore /etc/ioconfig  from backups.

 

But if you need to recreate the ioconfig files, here's how:

Boot the system to single user mode. Then, mount the root filesystem in read/write mode and mount /stand.

Then run "/sbin/ioinit -c" and reboot. The system may reboot automatically one more time while recreating the ioconfig files: this is normal.

Re: server booting error

Hi Matti,

 

Thanks you very much, Now i corrected the fstab entry after that server booted successfully.

 

Thanks you, thanks once again.
