Re-checked.. /dev/discs seems to be based on /dev/ide/-mapping and yet |
| 19 |
they are not complete: |
| 20 |
|
| 21 |
magrathea ~ # find /dev/ide -name disc -o -name cd |
| 22 |
/dev/ide/host0/bus0/target0/lun0/disc |
| 23 |
/dev/ide/host0/bus0/target1/lun0/disc |
| 24 |
/dev/ide/host0/bus1/target0/lun0/cd |
| 25 |
/dev/ide/host0/bus1/target1/lun0/disc |
| 26 |
/dev/ide/host2/bus0/target0/lun0/disc |
| 27 |
/dev/ide/host2/bus0/target1/lun0/disc |
| 28 |
/dev/ide/host4/bus0/target0/lun0/disc |
| 29 |
/dev/ide/host4/bus1/target0/lun0/disc |
| 30 |
/dev/ide/host4/bus1/target1/lun0/disc |
| 31 |
|
| 32 |
so /dev/ide/host/bus0/target1/lun0/disc (which ought to be /dev/hdj) is |
| 33 |
missing there. |
| 34 |
But see the listing in sysfs: |
| 35 |
|
| 36 |
magrathea ~ # find /sys/bus/ide/drivers/ide* -type l | sort -k 7 -t / |
| 37 |
/sys/bus/ide/drivers/ide-disk/0.0 |
| 38 |
/sys/bus/ide/drivers/ide-disk/0.1 |
| 39 |
/sys/bus/ide/drivers/ide-cdrom/1.0 |
| 40 |
/sys/bus/ide/drivers/ide-disk/1.1 |
| 41 |
/sys/bus/ide/drivers/ide-disk/2.0 |
| 42 |
/sys/bus/ide/drivers/ide-disk/2.1 |
| 43 |
/sys/bus/ide/drivers/ide-disk/4.0 |
| 44 |
/sys/bus/ide/drivers/ide-disk/4.1 |
| 45 |
/sys/bus/ide/drivers/ide-disk/5.0 |
| 46 |
/sys/bus/ide/drivers/ide-disk/5.1 |
| 47 |
|
| 48 |
and the listing from dmesg: |
| 49 |
|
| 50 |
magrathea ~# dmesg | grep ^hd | grep drive |
| 51 |
hda: Maxtor 4D040H2, ATA DISK drive |
| 52 |
hdb: SAMSUNG SP1614N, ATA DISK drive |
| 53 |
hdc: IDE-CD R/RW 16x10A, ATAPI CD/DVD-ROM drive |
| 54 |
hdd: Maxtor 92041U4, ATA DISK drive |
| 55 |
hde: Maxtor 4G120J6, ATA DISK drive |
| 56 |
hdf: Maxtor 96147H6, ATA DISK drive |
| 57 |
hdi: SAMSUNG SP1614N, ATA DISK drive |
| 58 |
hdj: IC35L040AVER07-0, ATA DISK drive |
| 59 |
hdk: SAMSUNG SP1614N, ATA DISK drive |
| 60 |
hdl: SAMSUNG SP1614N, ATA DISK drive |
| 61 |
|
| 62 |
And hdparm iterates through /dev/ide/* if found... |
| 63 |
Is /dev/ide according to LSB? Or is this also supposed to vanish? ;-) |
| 64 |
Then I'll have to file a bug for hdparm instead :) |
