HP/UX system administration




HP/UX system administration


Basic usage
Check system version, release and patches,
uname -r
swlist -l bundle | grep ' OS'
swlist -l bundle | grep ' Operating Environment'
swlist -a state -a patch_state PH*
Note. B.11.11 = 11i
Note. B.11.23 = 11i v2
Note. B.11.31 = 11i v3

Check for CPUs,
ioscan -fnkC processor
top

Check for memory and swap,
swapinfo -a
dmesg | more  # search for Memory
top    # real + virtual + free

Check for disks,
ioscan -fnkC disk

Check for filesystems,
cat /etc/mnttab
bdf

Add some user and fix its shell,
useradd -m user1
passwd user1
chsh user1 /usr/local/bin/bash

If you desperately need more space,
fsadm -b 1048576 /var
fsadm -b 4194304 /usr
fsadm -b 5242880 /opt
lvreduce -L 1024 /dev/vg00/lvol8
lvreduce -L 4096 /dev/vg00/lvol7
lvreduce -L 5120 /dev/vg00/lvol6
Note. if you also want to resize /stand, you may try with "-C y" and "lvlnboot -r" thereafter.


Package management
View some product content,
swlist -l product | grep -i cde
swlist -l fileset CDE
swlist -l file CDE.CDE-MIN

Install products,
gunzip mutt-1.5.20-ia64-11.23.depot.gz
unset DISPLAY
swlist -s /root/mutt-1.5.20-ia64-11.23.depot
swinstall -s /root/mutt-1.5.20-ia64-11.23.depot mutt

If you experience errors, check the logs,
cd /var/adm/sw/queue/logfiles
cd 000X
more logfile
remove the failed software install,
swremove BUNDLE
and try again, once you fixed the issue,
swinstall /absolute/path/to/BUNDLE


HBA configuration & multipathing
Display hard drives & LUNs,
ioscan -fnC disk
Note. "-funC" for "usable" disks
Note. "insf" or "insf -e -C disk" to force device creation
Note. "-k" as user

Display Fiber Channel adapters,
ioscan -fnC fc
display the HBA's WWN,
fcmsutil /dev/fcd0
note. "/dev/fcdX" or "/dev/tdX"
check for LUNs,
ioscan -fnC disk

For HP/UX 11.23
Configure PVLink (11.23 - Path failover through LVM). Once your VG is working on one path (PV needs to be created on one of the paths first, see the "LVM configuration" paragraph), add the alternate paths to it,
vgextend vg01 /dev/dsk/c2t0d1 /dev/dsk/c6t0d1 /dev/dsk/c8t0d1
Note. otherwise purchase and use SecurePath

For HP/UX 11.31
SAN Multipath option comes with OS. The new storage stack includes dynamic multipath balancing.


Backup/restore
To recover files to original location,
frecover -f /dev/rmt/0m -xov -i /source_directory

To recover files relative to the current working directory:
cd /destination_directory
frecover -f /dev/rmt/0m -xXov -i /source_directory

Refs.


Single user mode
Interrupt the bootloader timeout and boot single user,
boot -is vmunix

Define PATH, TERM and proceed...,
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin
TERM=vt100
export PATH TERM
...
Note. if you have bash installed,
/usr/local/bin/bash
Note. if you need to use LVM,
vgchange -a y VGNAME
Note. switch to init 3,
sync
init 3


Misc
Get a decent environment with the default shell and vars,
stty erase ^?
export TERM=xterm

Check the logs,
tail -f /var/adm/syslog/syslog.log
tail -f /var/adm/syslog/mail.log

Shutdown,
cd /
shutdown -h -y now
reboot,
cd /
shutdown -r -y now
#reboot

To give an alternate default shell for all normal users,
vi /etc/profile
add,
if [ $LOGNAME != root \
-a $LOGNAME != daemon \
-a $LOGNAME != bin \
-a $LOGNAME != sys \
... ]; then
command
fi

To add the rc.local feature to HP/UX,
cd /sbin
vi rc
add at the end,
/bin/ksh /etc/rc.local
then your rc.local script,
cd /etc
vi rc.local
like e.g.,
#!/bin/ksh
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:$HOME/bin\
:/usr/local/apache2/bin:/usr/local/mysql/bin
export PATH

print "starting mysqld"
mysqld_safe --user=mysql &

print "starting apache2"
apachectl start
fix perms,
chmod 755 rc.local

Instead of "diff -r", use,
dircmp -s -d folder1 folder2 2>&1 | more
Note. this only works directory per directory.

Check if only space & tabs:
od -c file

Free the 80 port,
cd /opt/DevMan
vi DevManBE.ini
changer,
[Service]
AutoStart=1
Fresh Install=0
[Web]
Port=8081
apply,
cd /sbin/rc3.d
./DevMan stop
./DevMan start

To mount an ISO image on HP/UX 11.31 (11iv3),
lvcreate -n cdrom -L 5000 vg00
cd /var/tmp
dd if=image.iso of=/dev/vg00/rcdrom bs=4096k
  mkdir -p /cdrom
mount /dev/vg00/cdrom /cdrom
Note. lvcreate -L in MB
Note. dd against the raw device (rcdx)

To mount an ISO (w/ or w/o rockridge) on older HP/UX releases,
/usr/sbin/pfs_mountd &
/usr/sbin/pfsd &
then edit or create this file,
vi /etc/pfs_fstab
with the following contents:
/dev/dsk/c0t4d0 /ISO_CDROM pfs-iso9660 xlat=unix 0 0
/dev/dsk/c0t4d0 /ISO_RR_CDROM pfs-rrip xlat=unix 0 0
note. create the dirs,
mkdir /ISO_CDROM
mkdir /ISO_RR_CDROM
mount the CDrom,
pfs_mount /ISO_CDROM
ls -l /ISO_CDROM
umount the CDrom,
pfs_umount /ISO_CDROM
same with long filenames
pfs_mount /ISO_RR_CDROM
pfs_umount /ISO_RR_CDROM
