"Launching /stand/vmunix" freezes

[Miguel Silva Rentes]

Hi everyone,

I have several HP-UX machines on my workplace and one of them is not booting anymore. I'm trying to get to single user mode but the machine doesn't pass through this point:

HPUX> hpux -is /stand/vmunix
> System Memory = 4075 MB
loading section 0
.......................................................... (complete)
loading section 1
.............. (complete)
loading symbol table
loading System Directory (boot.sys) to MFS
....
loading MFSFILES directory (/stand/bootfs) to MFS
....................
Launching /stand/vmunix
SIZE: Text:29280K + Data:7015K + BSS:5240K = Total:41537K

I'm using MP card to issue a reset command and then choose single user mode. I can see from VFP that everything is ok (all green lights).  What could be the cause for this problem?

Please help.

From  ISL prompt try rebooting from previous kernel

To boot normally from the previous kernel, type:
"hpux (;0)/stand/vmunix.prev" and [return].

To boot in "single user" mode from the previous kernel, type:
"hpux -is (;0)/stand/vmunix.prev" and [return].

[Miguel Silva Rentes]

No luck.

HPUX> hpux -is (;0)/stand/vmunix.prev
Could not open file (;0)/stand/vmunix.prev to check for a directory
Could not open (;0)/stand/vmunix.prev

loading failed

or  if I do

HPUX> hpux -is /stand/vmunix.prev
Could not open file /stand/vmunix.prev to check for a directory
Could not open /stand/vmunix.prev

loading failed

Any help would be great, as I can't start HP-UX on this machine.

This is an Itanium machine!


2 things to check:

1) go to EFI and do

Shell> conconfig

Which is the primary console???

If VGA, you cannot anything from MP!

2) from the boot loader do

HPUX> boot backup -is

or

HPUX> boot vmunix -is

[Miguel Silva Rentes]

1) From EFI:

CONSOLE CONFIGURATION

  Index Primary Type    Device Path
  ----- ------- -----   ----------
    1      NC   Serial  Acpi(HWP0002,PNP0A03,0)/Pci(1|2)
    2      P    VGA     Acpi(HWP0002,PNP0A03,700)/Pci(1|0)
    3      NC   VGA     Acpi(HWP0002,PNP0A03,0)/Pci(3|0)

Do I have to change to Serial? I thought I could see everuthing from Console on MP, just like if I had a monitor connected to the server.

2) HPUX> boot backup -is
Boot path is now: backup/vmunix
> System Memory = 4075 MB
loading section 0
.......................................................... (complete)
loading section 1
.............. (complete)
loading symbol table
loading System Directory (boot.sys) to MFS
....

....................
Launching /stand/backup/vmunix
SIZE: Text:29235K + Data:7014K + BSS:5240K = Total:41490K

After 10 minutes it shows me no progress.

3) HPUX> boot vmunix -is
> System Memory = 4075 MB
loading section 0
.......................................................... (complete)
loading section 1
.............. (complete)
loading symbol table
loading System Directory (boot.sys) to MFS
....
loading MFSFILES directory (bootfs) to MFS
....................
Launching /stand/vmunix
SIZE: Text:29235K + Data:7014K + BSS:5240K = Total:41490K

The same result (no progress) if I run with "boot vmunix -is".

The console is the problem.


While in boot up, the screen is mirrored to all output devices (VGA+serial), but when starting hp-ux the output is ONLY on the primary console.

This means VGA is the console at the moment, so you cannot see any output via MP!!!

In other words, your system currently boots up, but you cannot see this process, because your console is dead (not configured).

Set the serial to primary and it will work.

Problem solved. I changed the Console configuration to Serial and saw from MP (Console) that the server booted with a problem on one filesystem (it was full).

Thanks.

Hello,

Could you provide more details on how to "Set the serial to primary" so that I can also get past the "Launching /stand/vmunix" from an MP telnet session? (After the server boots up, I can reach it via ssh.)

If doing this, will I then be able to do a DVD cold-install from an MP Telnet session? When I tried,  I observed the installation going smoothly until the screen display asking the user to input the keyboard type. (I had to complete the installation in the office with the monitor hooked to the VGA port.)

Thanks,

   Paul

Thank you for the details. I am new to EFI.
