hdparm doesn't seem to report, for SCSI drives, the asme stuff it does
for IDE drives. I'm specifically looking to see if DMA transfers are on
or off. I presume since I don't see a "using_dma" attribute that it
doesn't apply to SCSI???
IDE:
/sbin/hdparm -vt /dev/hda
/dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/16/63, sectors = 156301488, start = 0
Timing buffered disk reads: 96 MB in 3.00 seconds = 31.97 MB/sec
SCSI:
/sbin/hdparm -vt /dev/sda
/dev/sda:
readonly = 0 (off)
geometry = 4420/255/63, sectors = 71020544, start = 0
Timing buffered disk reads: 64 MB in 1.43 seconds = 44.76 MB/sec
