DSMC does not start.

[djeyie]

Hi,
We are using TSM 5.2.1 in AIX 5.2 .
We tried to apply a apar to one of our server which also runs AIX 5.2 .
It previously had the TSM client running perfectly fine and now after applying the apar from IBM which was for OS level fix, and rebooting the server, DSMC wouldn't come up.

When we type dsmc in the command line, it would stay still.
We also checked with the AIX apar which did not affect any of the tivoli packages.

It happens in two of our server which were in cluster environment.
Please advice. It is business critical to us.

Thanks & Regards,
Dominic Jeyie A

Any reason why you're still on TSM 5.2.1?

Hi,
I have tried with dsmc -optfile=(path)/dsm.opt

Still it hangs .

Thats a good question "Any reason why you're still on TSM 5.2.1? "
I have suggested to my clients regarding upgrades...
They are working on it... :redface:

The entries on dsmerror.log is :
18/06/08 09:01:20 ANS1977E Dsmcad schedule invocation was unsuccessful - will try again.
18/06/08 09:18:57 cuGetAuthResult: Authorization failed. Result code: 2
18/06/08 09:18:57 sessOpen: Error 137 from signon authentication.
18/06/08 09:18:57 ANS1051E Invalid password

It never prompted for any password .

What shall I do now ?

 

[heada]

Verify that "passwordaccess generate" is set in the dsm.sys file. (AIX uses dsm.sys for all options, not dsm.opt) and then go to the TSM server and update the password for that node. Then go back to the AIX client and use "dsmc q sess" as root. It should prompt you for the TSM password. It will then store that password in /etc/security/adsm/TSM.PWD

Hi Heada,
I checked it and updated the password .
Still it hangs :
tubairux1 > dsmc q sess

When I check the DSM process running on the machine it gives me :
tubairux1 > ps -ef |grep dsm
root 925828 1 78 10:00:50 pts/8 161:50 /usr/tivoli/tsm/client/ba/bin/dsmcad

I dont know what PID : 1069310 is running. I checked with all TSM backup process, there is no file backup running at this time.

Thanks in Advance .

Hi Heada,

Please let me know how to find out if the TSM client is running on 32 bit or 64 bit.

Also let me know how to trace dsmc for errors other than dsmerror.log

Thanks in advance .

 

[heada]

You have alot of dsmcad process running (normally there should only be 1).

The error message from the dsmerror.log file says that the CAD can't authenticate to TSM. I would clean up the processes, remove the encrypted client password file (/etc/security/adsm/TSM.PWD) and then set the password again with the dsmc q sess command.

Hi Heada,

Please let me know how to find out if the TSM client is running on 32 bit or 64 bit.

lslpp -l |grep -i tsm

That will list the installed filesets for TSM. The 64bit client should be listed with a 64 in it (been a while since I've worked with a 5.2 client)

You can check what AIX kernel you're running by using:

bootinfo -K

Also let me know how to trace dsmc for errors other than dsmerror.log

Thanks in advance .

dsmerror.log is actually fairly useful and normally gives all the information needed to diagnose a problem like this.

HI Heada,
We have the server in cluster environment. We have 4 resourse groups running on it. So we have 4 + 1 DSMCAD proces running.

When the first time I changed the password for the node, I checked with the file TSM.PWD. The last access date was last sep. Does it means that It has not updated the password .

Do I still need to go a head in deleting the pwd file?


Thanks in Advance.

 

[heada]

Are you using 4 different dsm.opt/dsm.sys files (one per resource group)? Since this is a HA setup, I'm not sure how TSM would store the encrypted password in the filesystem (4 files....1 file with 4 entries...) Once you throw HACMP into the mix, things get interesting. Since I don't know how TSM would handle the password storing in a HA setup, I'd suggest you call IBM on this one.

Hi Heada,
We are using 1 dsm.sys in the location :
/usr/tivoli/tsm/client/ba/bin/

4 dsm.opt in the locations like :
/tsm/rg01/dsm.opt
/tsm/rg02/dsm.opt
.
.
.
The password is same for the dsmc for all in one file in the location :

passworddir /etc/tsm/local/aix

IBM will not support this TSM version as it is outdated.
I am helpless here !

Thanks in Advance.

Hi,
I was able to fix the issue with the DSMC and DSMCAD.
I just scp ed all these files from TSM server to those affected server.
Now all of them are up and running.

I got another Problem with the backup.
We are using rman for backing up the Oracle 8i and 9i files.
There is no problem with the 8i databases.
9i databases are unable to be backed up.
They are unable to allocate channels for backup.

When we use parms "SBT_TAPE" , it does not allocate channels.
Can some one please tell what has to be done here ?
Is there any possibility of lib files being corrupted ?

Thanks in Advance .
