IC88058: UNEXPECTED TRANSPORT MODE MAY BE CHOSEN FOR BACKUP VM.

IBM Tivoli Storage Manager (TSM) Client 6.3.2 Downloads and READMEs

APAR status

• Closed as program error.

Error description

• The unexpected transport mode may be chosen for "backup vm" even
  though it is explicitly excluded from "vmvstortransport" or
  "-vmvstortransport" option string.
  
  For example, even though "vmvstortransport san" is specified in
  dsm.opt, "backup vm" may start using nbd transport (LAN)
  unexpectedly.   The following logs can be seen in the client
  trace file by specifying VM VM_DETAIL trace classes.
