24 Jul 15 Single user vg00 reconfiguration for a san boot hp-ux system

San boot system.

HBA has to be replaced.

Then you have to boot single user mode to re-establish all your paths.

Procedure authored by my colleague Mahesh Koduru

Before you start make sure you have a current map file hosted on root filesystem.

“Reboot the server and follow these steps :
Interrupt the boot and boot the system in maintenance mode.

fs0:\EFI\HPUX> hpux

HPUX> boot -lm –lq vmunix This will bring the System into Maintance mod

#vgdisplay vg00 The VG should be in deactivated Mod

#ll /dev/*/group Collect the Group file

#vgexport -p -s -m vg00.map /dev/vg00 Keep the Map file in present directory , ie root

# ll vg00.map
#vgexport -v /dev/vg00

#mkdir -m 755 /dev/vg00
#mknod /dev/vg00/group c 64 0x030000 ##This is an example your major/minor number may vary
#vgimport -s -N -m vg00.map /dev/vg00 ## The -N is B.11.31 only to convert to agile storage
#vgchange -a y vg00
#mount -a Mount only Root filesystems

#setboot Check and correct setboot issues

#lvlnboot -v vg00 Check and correct lvlnboot issues , lvrmboot command can be used if needed

#/usr/sbin/lvlnboot -v
# lvlnboot -r /dev/vg00 Execute for fixing Boot Labels
# lvlnboot -r /dev/vg00/lvol3
# lvlnboot -b /dev/vg00/lvol1
# lvlnboot -s /dev/vg00/lvol2
# lvlnboot -d /dev/vg00/lvol2
# lvlnboot -v
# lvlnboot -R

Note: Comment the swap in fstab and then issue below command.
# shutdown -ry 0

24 Feb 15 Server backplane layout for rx class servers

HP-UX hardware is a bit Byzantine in nature. The following script demystifies things a bit and allows us to work at remote data centers with accuracy on cable issues both fiber and copper.

If you want to use this script, use the contact form to reach out to me. Most people will find cutting and pasting from the website very frustrating.

I am also reaching out to the community, dare I say fan base for assistance. I am fairly certain that the fiber side accurately reports status of hba connections. I am fairly certain that the copper side needs to be improved.

This is tested on rx7640 and rx8640 systems. I am fairly confident that it will work on superdomes. I just do not happen to have any around to test on.

Script includes an environment plugin called .scriptenv . I will provide relevant code from it as some of what it does is customer specific and can not be released into the wild. If functionality is needed everywhere, I try to provide it via a centrally managed file. I provide functionality to both command prompts and scripting this way. It allows me to make the scripts generic and change one file with environment customizations.

Script is based on olrad -q output. It uses several deprecated utilities such as lanadmin and lanscan. Since I currently doubt HP-UX v4 is in the works, this should not be a problem.

The output then the script:

IP addresses and mac addresses have been changed to protect the innocent:

22 Oct 14 fun vpar facts: see vpmon/monitor boot disk path.

When running vpmon/vpar virtualization, any changes made to the vpar database vpardb are automatically saved to:

/stand/vpdb

In fact you can boot vpmon of a disk, stand up the vpars, and reven remove the original vpmon system and boot disk and the database will maintain integrity on the remaining systems.

To sync/verify the vpardb

vparstatus -D /stand/vpdb

vparstatus -m

Console path:  No path as console is virtual
Monitor boot disk path:  1.0.4.0.0.0.0.4.0.0.0.1.128.0.0.0.0
Monitor boot filename:  /stand/vpmon
Database filename:  /stand/vpdb
Memory ranges used:  0x0/349069312 monitor
0x14ce6000/327680 firmware
0x14d36000/417792 monitor
0x14d9c000/925696 firmware
0x14e7e000/1417216 monitor
0x14fd8000/50495488 firmware

0x79ffc000000/67108864 firmware
0x89ffc000000/67108864 firmware

will show you what hardware was actually used to boot the vpmon. You may find your monitor disk path no longer exists and your vpars are running just fine.

06 Nov 13 Getting EMC disk ID’s.

We want storage to check performance on three possibly problematic LUNS.

Need to get the 4 character LUN ID’s on three disks:

disk82 disk83 and disk123

/usr/bin/inq -nodots -sym_wwn | egrep “disk82|disk83|disk123″| awk ‘{print $3}’ |awk ‘{ print substr( $0, length($0) – 3, length($0) ) }’

25 Jul 13 Replacing a bad vxvm boot disk. HP-UX 11.23 PA-RISC

So you lose a boot disk on a vxvm booted system. You hot replace the disk, but now you need to make sure the software mirror is good.

 

Lets say for example its rootdisk02

If the disk stayed alive and did not power down you can run vxbrk_rootmirror and cleanly replace the disk.

What do do if the disk powered down?

/opt/VRTS/bin/vxdiskunsetup -C rootdisk02

vxrecover -g rootdg -sb

You more than likely end up with a disk named like this that is totally useless:

rootdg.26724.31359

vxdg destroy rootdg.26724.31359  (on rootdisk02)

 

Remove the incomplete mirror copy

 

/etc/vx/bin/vxbrk_rootmir -v rootdisk02

 

And mirror it back ,

/opt/VRTS/bin/vxrootmir -v -g rootdg rootdisk02

10 Sep 12 Hot replacement of an HBA/NIC card (rx8640). No downtime.

Take note of the fcmsutil output below. One of the fiber cards has failed here.

We became aware of the problem due to a resmon message and errors generated on the SAN side.

11 Jul 12 Online JFS filesystem expansion without umount

This requires add in software from Veritas/Symmantec that can be expensive on HP-UX.

Lets say we want to extend /var which is lvol8.

It was originally 600 LE and we extended it as follows.

lvextend -l 800 /dev/vg00/lvol8 /dev/disk/disk25_p2

The 800 refers to LE logical extents. I prefer to use this rather than MB because it corresponds to the values displayed by most lvm utilities. -L <value in megabytes> can be used. I assume you can do the math here.

[system099]/root # lvdisplay /dev/vg00/lvol8
— Logical volumes —
LV Name                     /dev/vg00/lvol8
VG Name                     /dev/vg00
LV Permission               read/write
LV Status                   available/syncd
Mirror copies               1
Consistency Recovery        MWC
Schedule                    parallel
LV Size (Mbytes)            12800
Current LE                  800
Allocated PE                1600
Stripes                     0
Stripe Size (Kbytes)        0
Bad block                   on
Allocation                  non-strict
IO Timeout (Seconds)        default

It was originally 600 LE and we extended it as follows.

lvextend -l 800 /dev/vg00/lvol8 /dev/disk/disk25_p2

 

fsadm -F vxfs -b 12800M /var

This command will use online JFS to extend the filesystem. The alternative is extendfs. But that requires a umount.  Or perhaps xvumount -o force. Your choice, I don’t recommend it, but did test it the other day in the sandbox.

Now if you want to be cute and use all your space, try this.

SIZE=$(lvdisplay /dev/vg00/lvol8 | awk ‘/LV Size/ {print $NF}’);

ESIZE=”${SIZE}M”

fsadm -F vxfs -b $ESIZE /var

You can get more cute and do it with a single command line but I’m not going to do that. I have not broken any systems this week and am trying to avoid that.

01 Jul 10 Quick and dirty awk trick to see all Fiber Channel status

I needed to update documentation and I needed more information that my prior syslayout.sh script provided on fiber.

# Improvement by JRF on the ITRC forums.

ioscan -kfnC fc | awk ‘/fcd/ {getline;fcd=$NF;print fcd,$2}’ | while read -r fdev
do

fcmsutil ${fdev} | awk ‘/Hardware / {print $5};/World / { print $7}’

done

Ouput looks like this:

0/0/12/1/0/4/0
0x5001438002a24979
0x5001438002a24978
0x204f000dec81b540
0x200f000dec81b541

0/0/12/1/0/4/1
0x5001438002a2497b
0x5001438002a2497a
0x2093000dec81b480
0x2010000dec81b481

2/0/12/1/0/4/0
0x5001438002a24d35
0x5001438002a24d34
0x2050000dec81b480
0x2010000dec81b481

2/0/12/1/0/4/1
0x5001438002a24d37
0x5001438002a24d36
0x2093000dec81b540
0x200f000dec81b541

Second, new improved version (Girsah Chadash)
ioscan -kfnC fc | awk ‘/fcd/ {getline;fcd=$NF;print fcd,$2}’ | while read -r fde
v
do

fcmsutil ${fdev} | awk ‘/Hardware / {print $5};/World / { print $7}’ | awk’ {printf “%s %s %s %s %s”,$1, $2, $3, $4, $5;}’
fcmsutil ${fdev} | awk ‘/Hardware Path/ {PATH=$5};
/N_Port Node/ {NNODE=$7};
/N_Port Port/ {NPORT=$7};
/Switch Port/ {SPORT=$7};
/Switch Node/ {SNODE=$7};
END{print PATH, NNODE, NPORT, SPORT, SNODE}’

done

Next innovation would be to combine the awk statements in the while loop and pull off the output with a single awk command. I may do this, but I might need help from an awk guru.

The ioscan output is multi line, so the real innovation is using the getline function of awk to get the second line of data and ignore the first. The filter /fcd gets rid of the column format information.

Yes it could be done with grep, but it is more AWKFUL this way.

Updated document to provide some indentation. Trying to make the code easier to read. That may force me to add formatted scripts to download, which I will get to as time permits.
