Help on UPDATE DEVCLASS -- FILE says about MAXCAPacity:

"The value specified should be less than or equal to the maximum
supported size of a file on the target file system."

Check whether this condition is met...

Subject: [ADSM-L] TSM DB backup question


Hi All,

Thanks for your help!!

In my daily maintenance schedule I am doing a database backup to disk
with the following call and using the following device class. When the
backup runs it writes a second file apparently after it completes the DB
backup.  I wouldn't be concerned except the extra file shows up in my
volume history as seen below (which I did not expect). Notice the entry
for the second file has the same Backup Series as the first file. It
looks like TSM is writing a second volume since the Volume Sequence is
2, but I dont know why!

NOW I SEE IT!  The Est/Max Capacity (MB): 61,440.0 is getting me. I
created this device class and I don't remember putting a size on it but
I guess I did. Anyway, when I try to change it to 80000Mb TSM tells me:

---
ANR2017I Administrator ADMIN issued command: UPDATE DEVCLASS DBBTOFILE
MOUNTL=20 DIRECTORY=/tsmdbb MAXCAPACITY=80000M SHARED=NO
ANR8366E UPDATE DEVCLASS: Invalid value for MAXCAPACITY parameter.
---
I tried to schnge the mount limit to 1 instead of 20 and got the same
thing
---
ANR2017I Administrator ADMIN issued command: UPDATE DEVCLASS DBBTOFILE
MOUNTL=1
DIRECTORY=/tsmdbb MAXCAPACITY=80000M SHARED=NO
ANR8366E UPDATE DEVCLASS: Invalid value for MAXCAPACITY parameter.
---
Anyone know why. I tried it from command line and the ISC ang get the
same message in the ACTLOG.
