swinstall problem

Troyan Krastev — Mon, 30 Jul 2001 15:36:56 GMT

Hi all,

When I try to install some software on my N class server (swinstall) I get message ?The controller has lost communication with the agent?? during ?Executing Postinstall?. I tried recommendations from Doc ID W3555617 but it doesn?t help! With software that don?t have post install procedure it works fine.

Please Help,
Troy.

Hi Troyan:

This sounds as if transient network "issues" are interfering with 'swinstall'. If Measureware is running, this can interfer with a swinstall session.

I'd restart the 'swagentd' daemon and then try running 'swinstall" with this option:

# swagentd -r

# swinstall -x rpc_binding_info=ncadg_ip_udp:[2121]

...JRF...

We had, years ago, intermitent problems with swinstall and we can solve them adding these lines at the end of file in /var/adm/sw/defaults file.

swinstall.rpc_binding_info=ncacn_ip_tcp:[2121] ncadg_ip_udp:[2121]
swinstall.rpc_timeout=5
swinstall.retry_rpc=9
swinstall.agent_timeout_minutes=10
swinstall.polling_interval=60

Then execute:
swagentd -r

for restar swinstall daemon, you can also do /sbin/init.d/swagentd stop and /sbin/init.d/swagentd start

I hope it help you

Hi James,

swagentd is running with option "-r". I stopped all MeasureWare
related processes:
/sbin/init.d/mwa stop
midaemon -T
ttd -k
opcagt -kill
and started swinstall with option you gave me! The result is the same.

The recommendations so far would also been my first guess. :(

Some questions:

- Do you use a special Software Distributor (SD) software (Openview Software Distributor or the one provided with Service Control Manager software)?
- Do you have a patch for the normal SD installed? The last one for 11.00 is: PHCO_23966.

Make sure you didn't install a patch for the normal SD, if you use a special version.
If you don't use a special SD, install the latest patch.

You might want to enable debugging to get more logs?

# export SDU_DEBUG=1
# swagentd -r
# swinstall ....

logs go to stdout and to /var/adm/sw/*.log

To disable debug

# unset SDU_DEBUG
# swagentd -r

Hi Troyan

Are you using some fibres in the machine for SAN backups or are they connected to Brocade switch . In that case please disconnect the cable or recycle the power sequence after the server is on.

I crawled through some data and found that there were at least 2 cases addressed to HP where EMC Powerpath failed to install with swinstall.

The issues were not properly documented, but it appears that there were problems with the EMC Powerpath installation scripts.

Without blaming EMC at this point (the documentation I found is really missing too much), I suggest to contact EMC whether they know this issue.

I would also try the following:

1) copy the EMC s/w to a local depot on the server (e.g. /var/spool/sw)
2) find the postinstall script (should be in /var/spool/sw/catalog//pfiles) in this local depot and check it out. Does it exist? Does it perform valid steps?

Hi Carsten,
I attache *.log files from 3 installation sessions ( from CD and from local depot directory). It seems (the end of swagent.log) I get the error before running the config script. I attache one more file with SD versions,
this is standard distributor that comes with HP-UX11.0. I will try the DEBUG option you gave me.

Hi Manoj,
I really use fibres to connect to the EMC but the problem is in installation
it self. I called HP and they know about the problem, but no solution yet.

HI
I have faced the same problem with same EMC power path software.
Though EMC says it's fixed in ver 2.0 it still occurs
Here is solution to this.
Copy the powerpath software to some area on your disk .

Fix:PowerPath 2.0 can be installed by editing install scripts in the PowerPath 2.0 package:
The install scripts are located in PowerPath common directories. The scripts of concern are the preinstall scripts at:
EMCPower.HP.2.0.0_b094/catalog/EMCpower/PowerPath_common
EMCPower.HP.2.0.0_b094/catalog/EMCpower.2/PowerPath_common
EMCPower.HP.2.0.0_b094/catalog/EMCpower.3/PowerPath_common
Comment-out the following lines in all instances of the preinstall scripts:

???'swmodify -u EMCpowerpatch'
??-- and --
???'swmodify -u EMCpower'

-----------
The above lines are more than one place in same script, comment them all.
It worked for me.
Thanks.
Prashant.

Deshpande, thx for the clarification. I updated our internal databases with this information.
