I get the following when trying to restore a database on a new node
from a backup on another node:

RESTORE DB ocr3_p USE TSM OPTIONS "-fromnode dhu003p_db2" TAKEN AT
20060307022104 INTO ocr_o NEWLOGPATH /work/ocr_o/ocr_o/db2logs/NODE0000
REPLACE EXISTING REDIRECT WITHOUT ROLLING FORWARD
SQL2062N  An error occurred while accessing media
"/work/ocr_o/sqllib/adsm/libtsm.a".  Reason code: "406".

1) I'm not sure what TSM(?) reason code 406 signifies.
2) I've been changing the contents of the dsm.opt file to no avail
     servername      DMNSSC00
     virtualnodename dhu003p_db2         <== 'old' node
   or
     servername      DMNSSC00
     virtualnodename DB2SRV1-O_DB2         <== 'new' node

Please, can anyone help?

Thank you.
