I'm looking for an application that would allow me to send SCSI
commands to a SCSI device. Not only INQUIRY or TEST UNIT READY, but
ALL commands.
I already know about the sg_utils but it doesn't allow me to send out
commands like MODE SENSE/SELECT or RESERVE.
I could write my own application or extend the sg_utils but I wanted
to know if someone has been working on that already.
Thanks
Fred

Two suggestions:
[1] Take a look at the Linux SCSI driver code and header files
[2] Google search on "Linux SCSI driver"

1. Sending SCSI commands to 'claimed' devices...
hello all,
Is it possible to send SCSI commands to devices that are busy (local
disk, mounted disks, disks claimed by LVM etc.)?
I tried to send SCSI INQUIRY command to devices that were 'claimed' but
the command failed. The command worked
when the device was not claimed. The following were the ioctls I tried:
==============================================================
No. Disk IOCTL Remarks
==============================================================
1. Fixed SCSI disk DKIOCMD device cannot be opened
in diagnostic mode
2. Fixed SCSI Disk SCIOLCMD could not send SCIOSTART
3. Other FC Disk DKIOLCMD device cannot be opened
in diagnostic mode
4. Other FC Disk SCIOLCMD could not send
SCIOLSTART
==============================================================

Vikram
