System Administration Guide: Devices and File Systems

Accessing iSCSI Disks

If you want to make the iSCSI drive available on reboot, create the file system, and add an entry to the /etc/vfstab file as you would with a UFS file system on a SCSI device.

After the devices have been discovered by the Solaris iSCSI initiator, the login negotiation occurs automatically. The Solaris iSCSI driver determines the number of available LUNs and creates the device nodes. Then, the iSCSI devices can be treated as any other SCSI device.

You can view the iSCSI disks on the local system by using the format utility.

In the following format output, disks 2 and 3 are iSCSI LUNs that are not under MPxIO control. Disks 21 and 22 are iSCSI LUNs under MPxIO control.
