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

VG Version 1.0 <----- Proof :-)
VG Max Size 40t
VG Max Extents 1310720
--------------------------------------
# Step #1. From experience, we *know* that each current disk in the VG will
# need to have at least one free extent at the end to accomodate the transition
# to VG Version 2.x.
#
# But, currently, all extents from all current disks are allocated.
# We can move off 'N' number of extents from the end of the current
# disk to a new disk using the "-e" option of the pvmove command.
#
# (note: we use dsf's for all commands)
--------------------------------------
#
# First we need to unmount all filesystems
#
umount /bb/9/dev/mylab
umount /bb/9/dev/venturelab
umount /bb/9/dev
--------------------------------------
#
# Ok, we need to free up at least one extent from the end of
# the original, fully-qualified disks.
#
# We use the "-e" option of the pvmove command to make this happen.
# pvmove -e 2 /dev/disk/disk247 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk248 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk251 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk249 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk260 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk259 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk258 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk261 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk262 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk263 /dev/disk/disk265
# pvmove -e 2 /dev/disk/disk264 /dev/disk/disk265
#
# At this point, a vgdisplay should show at least 2 extents for each physical volume.
# Check our work
#
# vgdisplay -v /dev/vgscott01
--------------------------------------
# vgversion -r -V 2.1 /dev/vgscott01
#
# We are good to go!
#
#
# We need to deactivate the Volume Group before we can upgrade
#
# vgchange -a n /dev/vgscott01
#
# We are good to go!
#
# vgversion -V 2.1 /dev/vgscott01
--------------------------------------
#
# Check our work
#
# vgchange -a y /dev/vgscott01
# vgdisplay -v /dev/vgscott01
--------------------------------------
#
# Now, we can extend our logical volume
#
# lvdisplay /dev/vgscott01/lvol1
# lvextend -l 98864 /dev/vgscott01/lvol1
# fsadm -F vxfs -b 3163648m /bb/9/dev
--------------------------------------
# lvdisplay /dev/vgscott01/lvol1

# vgcfgbackup /dev/vgscott01

# mount /bb/9/dev
# mount /bb/9/dev/mylab
# mount /bb/9/dev/venturelab

Learning something new is great. Joe Geiger taught me something cool that I should have learned years ago.
Serviceguard users ever wanted to script a cluster change such as a node add.
cmapplyconf -v -P <package file>
Ends with a y/n prompt do you want to apply? Normally that requires input. Not with the yes command:
cmcheckconf -v -P <package file>
rc=$?
# Check return code if not zero stop
if [ ${rc} -ne 0 ]
then
echo “Checkconf error ${rc}”
exit ${rc}
fi
yes | cmapplyconf -v -P <package file>
# Check return code here as well

Script for detecting APA network bonded pairs. It is already built into the cinam21t drd image. It will save you 3-5 hours of guess work on future builds.
Networking was changed to protect the innocent.
Here is an example:
[root@cinam21t]:/home/root # ./apanetwork_discover 142.18.1.26 142.18.1.96 ——————————————————— -This script figures out which NIC cards are APA paired.- -It has two inputs:……………………………….- -1- The assigned IP address of the APA Group lan90#…..- -2- The known network address of an HP-UX server on net.- -ex ./apanetwork_discover 142.18.1.26 142.18.1.96 ……- – These are cinam21t and stlam31t…………………..- – The system must be OFF network for this to work ……- – Instruction: …………………………………..- – /sbin/init.d/net stop …………………………..- – /sbin/init.d/vlan stop ………………………….- – /sbin/init.d/hplm stop ………………………….- – /sbin/init.d/hpapa stop (You may need to ctrl-break…- – netstat -rn (ifconfig lan# down then unplumb any lans.- – Wash,rinse and repeat for lan901,lan902,lan903 …….- ——————————————————— The LAN is lan0 Success lan0 as 142.18.1.26 was able to ping 142.18.1.96 The LAN is lan8 NO JOY lan8 as 142.18.1.26 was able NOT to ping 142.18.1.96 The LAN is lan16 NO JOY lan16 as 142.18.1.26 was able NOT to ping 142.18.1.96 The LAN is lan19 NO JOY lan19 as 142.18.1.26 was able NOT to ping 142.18.1.96 The LAN is lan2 NO JOY lan2 as 142.18.1.26 was able NOT to ping 142.18.1.96 The LAN is lan49 NO JOY lan49 as 142.18.1.26 was able NOT to ping 142.18.1.96 The LAN is lan52 NO JOY lan52 as 142.18.1.26 was able NOT to ping 142.18.1.96 The LAN is lan56 Success lan56 as 142.18.1.26 was able to ping 142.18.1.96 [root@cinam21t]:/home/root # |
In this case lan0 are in the bonded pair (lan900)

Troublehooting steps:
1- Remove the /var/opt/perf/ttd.pid and try to start glance again
#rm /var/opt/perf/ttd.pid
#glance
2- If the above fails to fix it then stop and restart Glance as follows
# mwa stop
# midaemon -smdvss 4M -kths 1000 -pids 5000 -p # ps -ef | grep midaemon Make sure the midaemon is running, # mwa start
Modify MWA_START_COMMAND variable in /etc/rc.config.d/ovpa as follows to keep the changes across system reboot.
# grep MWA_START_COMMAND /etc/rc.config.d/ovpa MWA_START_COMMAND=”/opt/perf/bin/midaemon -smdvss 4M -kths 1000 -pids 5000 -p ; /opt/perf/bin/mwa start”
