OOOOOPPPPS!
I made a mistake in the table. The corrected table is listed below with
asterisks to note where the typo used to be.
Standard PDT Type Command
SBC 00 Disk READ CAPACITY
SBC 04 WriteOnce None (see note 2)*
SBC 07 Optical None (see note 2)*
SSC 01 Tape None (see note 1)
SSC 02 Printer None
SPC-2 03 Processor None
MMC-2/3 05 C/DVD None (see note 2)
SMC 08 MediumChanger None (see note 3)
SCC-2 0C Controller None (see note 4)
SES 0D Encl. Services None
RBC 0E ReducedDisk READ CAPACITY
SCSI-2 06 Scanner None
SCSI-2 09 Communications None
OCRW 0F (didn't find this draft)
Note 1: I might be convinced that PAM needs to know the
REPORT DENSITY SUPPORT (MEDIA=0)data, but one
can argue that PAM will grant some (set of) initiators access
to this device and only they really need to know this information.
Note 2: Since this is typically removable media, stuff
like READ CAPACITY and READ FORMAT CAPACITIES
would only be informative for the initiators using the device
and not for PAM for allocation of the device as a resource.
