ia64 boot loader?

Doug O'Leary — Tue, 11 Dec 2012 19:18:36 GMT

Hey;

All of the documentation on ia64 mirroring says the boot loader on the vg00/OS disks should say something like "boot vmunix"; however, I'm at a client site who's root disks are saying hpux, like the pa-risc systems. Obviously, this works as these systesm have booted. Is this a relatively new thing? Should they still say 'boot vmunix' or is that entry wrong now?

# model
ia64 hp Integrity rx2800 i2
# uname -r
B.11.31
# setboot | grep -i bootpath
Primary bootpath : 0/0/0/1/0/0/0.0x0.0x1030000c0000000 (/dev/rdisk/disk2)
HA Alternate bootpath :
Alternate bootpath : 0/0/0/1/0/0/0.0x0.0x1000000c0000000 (/dev/rdisk/disk3)
# lifcp /dev/disk/disk2_p2:AUTO -
hpux
# lifcp /dev/disk/disk3_p2:AUTO -
hpux

I'm assuming the alternate boot disk should still have the ignore quorum option, right? If you're booting off the alternate disk, chances are the primary isn't there anymore...

Thanks for helping me clarify this; I appreciate it.

The entries in LIF are still there for compatibility, but the boot file is in EFI.

Check like this:

# efi_cp -d /dev/rdsk/c2t1d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.pri

# efi_cp -d /dev/rdsk/c3t2d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.alt

# cat /tmp/AUTO.pri

# cat /tmp/AUTO.alt

my notes have:

# mkboot -a "boot vmunix -lq" /dev/rdisk/PRIMARY

# mkboot -a "boot vmunix -lq" /dev/rdisk/SECONDARY

At the HP-UX level you are looking at, I think this is correct.

For example:

11.31 root /root # lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/disk/disk41_p2 -- Boot Disk
/dev/disk/disk5_p2 -- Boot Disk
Boot: lvol1 on: /dev/disk/disk41_p2
/dev/disk/disk5_p2
Root: lvol3 on: /dev/disk/disk41_p2
/dev/disk/disk5_p2
Swap: lvol2 on: /dev/disk/disk41_p2
/dev/disk/disk5_p2
Dump: lvol2 on: /dev/disk/disk5_p2, 0

11.31 root /root # lifcp /dev/rdisk/disk5_p2:AUTO -
hpux

11.31 root /root # lifcp /dev/rdisk/disk41_p2:AUTO -
hpux
11.31 root /root # model
ia64 hp server rx2660

However the "boot vmunix" option is what is run from EFI. For example:

EFI Boot Manager ver 1.10 [14.61] Firmware ver 2.31 [4411]

Please select a boot option

HP-UX Primary Boot: 0/1/1/1.0x2.0x0

EFI Shell [Built-in]

System Configuration Menu

Use ^ and v to change option(s). Use Enter to select an option
Loading.: HP-UX Primary Boot: 0/1/1/1.0x2.0x0
Starting: HP-UX Primary Boot: 0/1/1/1.0x2.0x0

Hey;

thanks for the replies.

>>The entries in LIF are still there for compatibility, but the boot file is in EFI.

You know, I actually knew that... get out of supporting HPUX for a few months and you forget the easy stuff.

So, still have a problem, I think:

# model
ia64 hp Integrity rx2800 i2
# uname -r
B.11.31
# setboot | grep bootpath
Primary bootpath : 0/0/0/1/0/0/0.0x0.0x1030000c0000000 (/dev/rdisk/disk2)
HA Alternate bootpath :
Alternate bootpath : 0/0/0/1/0/0/0.0x0.0x1000000c0000000 (/dev/rdisk/disk3)
# efi_cp -d /dev/rdisk/disk2_p1 -u /EFI/HPUX/AUTO /tmp/auto.pri
# efi_cp -d /dev/rdisk/disk3_p1 -u /EFI/HPUX/AUTO /tmp/auto.alt
# cat /tmp/auto.pri
hpux -lq
# cat /tmp/auto.alt
boot vmunix -lq

The primary is saying "hpux -lq". I'm assuming that's failing on boot and this guy is booting off of the alternate. Does that sound accurate?

Thanks again for the replies. Apologies for the part-timerz question.

I assume the same. Check syslog for the message about the disk used for boot - it's the alternate?

Re: ia64 boot loader?

donna hofmeister — Tue, 11 Dec 2012 19:56:06 GMT

that's seems likely.

Does "dmesg" give any hints?

Re: ia64 boot loader?

Doug O'Leary — Tue, 11 Dec 2012 20:06:06 GMT

Hey;

dmesg's no help - system's been up for 166 days. I can't find any reference to either primary/alt in syslog.

I remembered that there was an adb command to find out from which disk a system was booted. A quick google search showed the ia64 version. Curiously enough, assuming accuracy, it's showing the disk that says hpux:

# efi_cp -d /dev/rdisk/disk2_p1 -u /EFI/HPUX/AUTO /tmp/auto.pri
# cat /tmp/auto.pri
hpux -lq
# ll /dev/disk | grep $(echo "bootdev/x"|adb /stand/vmunix /dev/kmem | awk '/0x/ {print substr($1,5)}')
brw-r----- 1 bin sys 1 0x000008 Feb 10 2011 disk2_p2

I'm going to get a chance to reboot this guy sometime soon... I'll have to watch the console.

Thanks again for the help/replies.

Try

$ grep -i "boot device" /var/adm/syslog/syslog.log

vmunix: Boot device's HP-UX HW path is: 0.4.1.0.5000c50002

Check the console log from MP too.

Re: ia64 boot loader?

Doug O'Leary — Tue, 11 Dec 2012 20:35:03 GMT

Hey;

Thanks for the string. That backs up the adb command string above:

# grep -i 'boot device' /var/adm/syslog/syslog.log
Jun 27 19:05:19 mercury vmunix: Boot device's HP-UX HW path is: 0/0/0/1/0/0/0.0x0.0x1030000c0000000
# setboot | grep 0/0/0/1/0/0/0.0x0.0x1030000c0000000
Primary bootpath : 0/0/0/1/0/0/0.0x0.0x1030000c0000000 (/dev/rdisk/disk2)
# cat /tmp/auto.pri
hpux -lq
# efi_cp -d /dev/rdisk/disk2_p1 -u /EFI/HPUX/AUTO /tmp/auto.pri

So, it seems like hpux is valid, at least in this specific case. I wonder if some bozo played games with the EFI shell to make that work. Any rate, I got the confirmation that I needed. Thanks again.

So maybe it has been changed since the last boot? You could look at the output of:

efi_ls -d /dev/disk/disk2_p1 /EFI/HPUX/AUTO

and look at the last modified date - changed since last reboot??

Hey;

I'm getting some good commands for the EFI shell, thanks.

Apparently, modified more than 166 days ago:

# efi_ls -d /dev/disk/disk2_p1 /EFI/HPUX/AUTO
FileName Last Modified Size
AUTO 1/20/2011 9

total space 523218944 bytes, free space 519286784 bytes

# uptime

Thanks again.
