I'm trying to run some scsi commands on our fc connection.
After opening /dev/fclp0, building the esctl_io structure for CMDinquiry, and using the SIOC_INQUIRY ioctl() call, I get back that SCSI is not supported on this device.
Figuring that I did something wrong, I downloaded the SG3-UTILS port from software depot, and ran:
# ./sg_persist /dev/fclp0
>> No service action given; assume Persistent Reserve In command
>> with Read Keys service action
inquiry: pass through os error: Invalid argument
sg_persist: /dev/fclp0 doesn't respond to a SCSI INQUIRY
Which at least made me feel a tad bit better - in that my simple program was getting the same result.
This of course begs the question - on 11.3i - how does one "talk scsi" on the fc? Pointers to documentation or other information greatly appreciated.
The /dev/fc* DSF is for the HBA (i.e. fro HBA management), it doesn't lead to the disk devices.
If you want to communicate to a disk device you must run the command against DSF mapped to the disk.
I.e. /dev/rdisk/diskX or maybe you'd need passthru device (depending on what exactly the command does),
which, if it doesn't exist, can be created by using something like this:
# ioscan -fknNC disk Class I H/W Path Driver S/W State H/W Type Description =================================================================== disk 1 64000/0xfa00/0x0 esdisk CLAIMED DEVICE HP Virtual Disk /dev/disk/disk1 /dev/disk/disk1_p3 /dev/rdisk/disk1_p2 ..
# mksf -H 64000/0xfa00/0x0 -P -r # ll /dev/pt/ total 0 crw-r----- 1 bin sys 12 0x000000 Nov 21 00:49 pt_disk1 # lssf /dev/pt/pt_disk1 esdisk section 0 at address 64000/0xfa00/0x0 /dev/pt/pt_disk1

Passthru is exactly what I'm looking for (I think).
So, if I understand correctly, I need to look at each entry in /dev/pt to determine which are connected by fc? Running the SCSI Inquiry command down each entry and parsing out the output - or doing the above shell commands in that same directory?
