serviceguard setup error on cmapplyconf

Amir Haboosheh — Wed, 16 Jul 2008 20:30:05 GMT

i am trying to setup a 2 node cluster. when i run:
# cmapplyconf -k -v -C /etc/cmcluster/clust1.config

i get this:
----------------BEGIN-------------------

vg01 is also my cluster lock.
when i run cmcheckconf everything checks ok and i don't get any errors.

Hi,

first activate vg01 (vgchange -a y /dev/vg01) then try cmapplyconf. After it works deactivate it with -a n and start the cluster.

Hi,

firstly we can check disk is ok with:

vgdisplay -v vg01
diskinfo /dev/rdsk/c2t0d1
pvdisplay /dev/dsk/c2t0d1
dd if=/dev/rdsk/c2t0d1 of=/dev/null bs=2048k

Salam Amir,

The message below may indicate that disk is not accessible.

WARNING: Cluster lock on disk /dev/dsk/c2t0d1 is missing!

ioscan -fnC disk--> see any unclaimed device

vgdisplay -v vg01
diskinfo /dev/rdsk/c2t0d1

Hi Amir

First you have to check the Health of disk
/dev/dsk/c2t0d1 and vg01 belongs to this disk.

hey gues, tanks for your replies. i have an open case with hp on this and they determined (after many days and logs and tests) that the problem is at the Storage or LVM layer.

my setup:
2x rx2660 FC conected to an MSA1500 with dual controllers. the MSA1500 has 1x MSA30 connect to it. both servers are connected to the MSA1500 with FC.

is this setup correct or do i need another MSA1500 (one for each server) and each MSA1500 will then be connected to the MSA30?

any help is appriciated, thanks you.

Hi,

Would post here the output of:

#ioscan -fnCdisk
#pvdisplay /dev/dsk/c2t0d1

Hi Amir,

I agree with all comments given here. As a first plan of action you please verify if disk is visible on both of your systems and also you can mount it before you actually go for running cmapplyconf next time.

Thank!

ok,
thank you guys for all the replies.
after 2 weeks of back and forth with hp serviceguard/LVM/Storage departments i found out that an MSA30 connected to an MSA1500 (w/ dual MSA1000 controllers) connected to an integrity server running hp-ux must be in an active/active firmware v.7 on the MSA1000 for it to work. active/passive does is not compatible unless you have a fiber switch in between.

thanks guys,
amir

Not exactly.

"OS Support for

...

HP-UX support
(specific guidelines)

The MSA1500 for HP-UX supports dual active/active controller or single controller configurations (Active/passive configurations are not supported). HP-UX single controller support is enabled with the standard firmware that ships with the MSA1500HP-UX implemented with dual active controllers requires use of firmware available through a free download off the MSA1500 web site.
NOTE: all MSA1500 HP-UX starter kits ship with active/active firmware pre-installed, which supports both single controller or active/active controller configurations.

ACU/CLI (Command Line Interface) is used for configuration and Event Monitoring Service (EMS) for monitoring.
Root/Boot/Dump/Swap/Install is also supported.
