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_id=0x60ba80 issue_scsi_inquiry..inq.lun_id=0x0 issue_scsi_inquiry..inq.status_validity=0 issue_scsi_inquiry..inq.scsi_status=0 issue_scsi_inquiry..inq.adapter_status=0 issue_scsi_inquiry..inq.flags=0 hexdump(): length=40 00 00 03 12 1f 00 00 32 4d 63 44 41 54 41 20 20 .......2 McDATA 56 54 4c 20 20 20 20 20 20 20 20 20 20 20 20 20 VTL 76 31 2e 30 00 00 00 00 v1.0.... call_inq: issue_scsi_inquiry returned rc = 0 call_inq: TSM doesn't support this type of a device. pdevtype=0 query_name_server: Trying Index = 0x2 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. .
