Comment 2 Joey Boggs 2011-09-28 12:51:03 UTC

This is data we pull from gudev, so it's not outputting correctly, will investigate this further


import gudev
client = gudev.Client(['block'])
for device in client.query_by_subsystem("block"):
    dev_name = device.get_property("DEVNAME")
    dev_serial = device.get_property("ID_SERIAL_SHORT")
    if "sd" in dev_name:
        print dev_name
        print dev_serial

Comment 3 Alan Pevec 2011-09-28 15:36:46 UTC

Leading "3" is coming from scsi_id, which was supposed to be source for udevdb

From scsi_id(8):
       Identifiers  based  on page 0x80 are prefixed by the character ’S’, the
       SCSI vendor, the SCSI product (model) and then the  the  serial  number
       returned by page 0x80. For example:

       # /lib/udev/scsi_id --page=0x80 --whitelisted --device=/dev/sda
       SIBM     3542           1T05078453

       Identifiers based on page 0x83 are prefixed by the identifier type fol-
       lowed by the page 0x83 identifier. For example, a  device  with  a  NAA
       (Name  Address  Authority)  type  of 3 (also in this case the page 0x83
       identifier starts with the NAA value of 6):

       # /lib/udev/scsi_id --page=0x83 --whitelisted --device=/dev/sda
       3600a0b80000b174b000000d63efc5c8c

Not sure how is ID_SERIAL_SHORT generated, but looking at udevdb I think ID_SCSI_COMPAT seems to be full wwid.
