shutdown -rn hangs

[Ionut Grigorescu_2]

Hi all,

I have a rp5470 box with HPUX11.i which hangs up by shutdown -rn - see below:
Stopping Internet Services ................................... OK
Stop NFS client subsystem .................................... OK
Stop NIS client subsystem .................................... OK
Stop NIS server subsystem .................................... OK
Stop NIS+ client subsystem ................................... OK
Stop NIS+ server subsystem ................................... OK

Unconfigure HP iether 100BT/Gigabit Ethernet interfaces ...... OK
Unconfigure HP igelan Gigabit Ethernet interfaces ............ OK
Stop network tracing and logging daemon ...................... OK
Stop pty allocator daemon .................................... OK
Stop system message logging daemon ........................... OK
Stop Software Distributor agent daemon ....................... OK
Unconfigure Loopback interfaces (lo0) ........................ OK
Stopping VERITAS Enterprise Administrator Service (vxsvc) ....
I don't know what is this vxsvc , I still have access to console and I can kill vxvsc but I don't know if it's safe so.

Thank you ,
ionu

That is used for the VxVM EA management interface (V3.5 of VxVM I believe).
It should not cause any issues if you do kill it.
There is a known issue with this, and there are various VxVM EA patches you install to fix this.
You could:
1) search omn the ITRC Patches to get any VxVM patches.
2) Install the latest Patch bundle from HP
3) log a call with your local HP RC to get the correct patches
4) visit http://support.veritas.com/docs/260954

Weve had problems with this vxvsc process also on 11.11 boxes - namely it running away and consuming 100% of a cpu on occasion for no apparent reason. After discussions with the HP Response centre we found out it is not needed if you are using LVM only (and not Vertias volume manager instead) so we disabled this process from running on all 11.11 servers and weve had no problems with it since! (remove the startup and shutdown symbolic links from /sbin/rc2.d/S999isisd and /sbin/rc1.d/K999isisd). HP will probably fix these problems with a patch for it at some point in the future so you wont have to disable it.

COnfig file of VXsvc is kept in /etc/vx/isis/Registry. May be you have some problem with the configuration. I suggest you to take a look at it using "vxregctl" tool.

Before that you can check the svc log file located at /var/vx/isis/vxisis.log for any errors.

Most importantly when you kill the process may be "vxisis.lock" remains there and gives you problem when you try to start the service again.

Hope this helps yuo more.

Thank you,

case closed.

Specifically, if you are running 11.11, you would want to install patchs PHCO_28651 and PHCO_28656.

The patches contain this note as well:

This patch majorly contains bug fixes of the VERITAS
Enterprise Administrator (VEA), which were done
between the VEA release 3.0.2.261 and the VEA release
3.0.2.272, as reported by different VERITAS point
products using VEA.

Best regards,

Thank-you for posting this problem Ionut. This thread just help me out!

I read this thread with a great deal of interest because my customer has an HP-UX 11.11 system that has hung at shutdown time exactly as described. The patches mentioned are not installed on this system because LVM is used, so I was considering disabling vxsvc as suggested above. My question centres around how I determine for sure that Veritas volume manager is not in use. My fstab lists file-systems of type "vxfs", my /var/vx/isis/vxisis.log file says "vxinstall has not been run".

What can I check to be certain that it is safe to disable the vxsvc service on this system?

Hi Mark,

it is save to disable this service if you are not using VXVM (Veritas Volume manager)

There a number of ways to verify if your disk are under LVM or VXVM control.

run next command
# vxdisk list

or check the ouput from the bdf command.

look at the "dev/vgxx" or the "/dev/vx/dsk/bootdg" in the above output.

Hope this helps,

Many thanks Robert-Jan that has cleared things up splendidly.
