19 Jul 22 Disk issues on HP-UX
So you are having disk problems:
Scenario 1:
You need to build a logical volume on a disk that is in the kernel. You have other issues that will not let you completely replace /etc/lvmtab
mv /etc/lvmtab /etc/lvmtab.save
vgscan -av
You need that disk number 967 to change.
ioscan -NfnCdisk shows the offending device files
/dev/disk/disk967
/dev/rdisk/disk967
64000/0xfa00/0x102
What to do?
Force the system to hand out new device files.
rmsf /dev/rdisk/disk967
rmsf /dev/disk/disk967
rmsf -H 64000/0xfa00/0x102
scsimgr -h lun_reset -D /dev/rdisk/disk967
insf -e
Possible alternative:
vgreduce -f /dev/vgname
Trick of the day if you are seing flapping on the SAN. Such as a scenario where deices are giong on and ofline.
ioscan -fN | wc -l ## Gets you a count.
drop the wc -l and you get a pretty detailed look at the HBA/SAN/disk infrastructure.
ioscan -fN
16 Dec 21 Linux vgs port for HPUX (updated to work with vg version 2.2)
A while back, I came across a port of the very nice linux vgs command for HP-UX. A h/t to Juan Manuel Rey (juanmanuel.reyportal@gmail.com) for that original version.
But, upon using it recently, I noted it was not working now that we have some volume groups with vg version 2.2. Here is a modified version of the script that works for version 2.2 volume groups!
#!/sbin/sh

# vgs.sh - script to emulate the Linux LVM command vgs in HP-UX 11iv3

28 Nov 17 An xpinfo that works in hpvm guests and on non Hitachi storage
Hitachi shops faced annoyance times two:
1. xpinfo does not work on non-Hitachi storage for example Pure storage
2. xpinfo does not work on hpvm guests depending on how the storage is passed through from the hpvm host
I now present xpinfonew which though raw and unfnished
The output:

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

29 Oct 14 Puzzle of the day. Strict logical volume prevents you from extending a filesystem
Thanks to Veerappan Dhandapani of HCL Technologies for bringing me this problem
You have 50 GB free in the volume group.
You try to extend the logical volume and you cant.
Basics:
1) bdf is the tool for measuring filesystem size not logical volume size
2)lvdisplay is the tool for measuring logical volume size.
Steps:
1) Extend the logical volume. That is why the previous two number points are important. In process after extending the logical volume size the lv size and file system size are not equal
2) Extend the file system.

We changed both to n(o).
