Server down---

[so_2]

Hi all

I have an hp9000 server which had a tape drive problem. We replaced the tape drive (it is an external dlt) but it has not detected by the server.hence we performed a reboot but after that the server is not coming up.

The server is located remote. We sked the onsite engineer to attend this and he is giving the followingerror messgae.
=============================================
Checked the server console (There is one - it's located on the EMC array next to the host) and the following message was being displayed.

-----------------------------------------------------------------------------------------------------------------
Boot
disc (12.6.0:0) /stand/vmunix
4837604 + 380928 + 2406688 Start 0x164568

Networking memory for fragment reassembly is restricted to 41598976 bytes
Logical volume 64, 0x3 configured as ROOT
-----------------------------------------------------------------------------------------------------------------

I restarted the host and the same message was displayed again.

I tried to boot the server into single user mode using the pripath (12.0.0) but it failed with the following message:

----------------------------------------------------------------------------------------------------------------
Boot
disc (12.0.0;0)s
disc (12.0.0;0)s: cannot open, or not executable
Exec failed: No such file or directory
----------------------------------------------------------------------------------------------------------------


I tried to boot the server using altpath (24.15.0) in both multi user mode & single user mode and received the same messages as above. The host an all external disk units were powered off before this was carried out but it made difference


I ran ODE and all disk related tests passed (there was a problem with the network loopback test)

The machine has been left at the ISL prompt

=====================================
could anyone suggest me what could be the problem?
It is saying could not open or not executable on both the primary and alt boot path. Do that mean kernel is missing?

Pls advise.

Thanks in advance

Hi SO,

external scsi tape drive attached to which scsi controller? Did you check the scsi id on the old tape drive and change the id on the new drive?

Regards,
Robert-Jan

[Torsten.]

"disc (12.0.0;0)s"

should look like

disk(12.0.0;0)/stand/vmunix

run single user mode:

ISL>hpux -is
or
ISL>hpux /stand/vmunix -is

Did you do that?

If this is a straight replacement, the most common issue is the SCSI ID not being correct.

before going single user mode, the SEA command should be used.

This will show a Sequential device if the tape drive is properly connected and no SCSI conflict exists.

You'd think hardware would get the SCSI ID right, but they don't always check. The drives themselves almost never ship with a useful scsi id.
