Error description

• The TSM device driver may fail to discover VTL devices attached
  to an AIX host.
  .
  Customer/L2 Diagnostics:
  A trace of the discovery process can be enabled by issuing the
  following command:
  .
     export CFG_DBG=1
  .
  From the same AIX shell where this command was issued, start
  SMIT and perform the device discovery process.  The trace data
  will be written to the smit.log file and may resemble the
  following:
  .
     issue_scsi_inquiry: Parent_fd=3
     issue_scsi_inquiry: SCIOLINQU successful,rc=0
     issue_scsi_inquiry..inq.inquiry_ptr->pdevtype=0x0
     issue_scsi_inquiry..inq.inquiry_ptr->vendor <McDATA VTL v1.0>
     issue_scsi_inquiry..inq.inquiry_ptr->product <VTL v1.0>

     issue_scsi_inquiry..inq.scsi_status=0

     query_name_server: sid =  0x60c100
     call_inq: issue start sid=0x60c100 lun=0x0
  .
  In the trace excerpt above we see that the TSM device driver
  issues the inquiry command against lun 0 on SCSI ID 0x60ba80.
  The inquiry command returns a device type of 0x0 (disk device).
  This results in a failure because disk is not a supported device
  type for the TSM device driver.  The TSM device driver does not
  proceed to look at the remaining luns on that SCSI ID as it
  should and, as a result, may fail to discover additional
  devices.
