Missing Solaris disks

飞天二狭

Missing Solaris disksSolaris' SCSI driver configuration file, /kernel/drv/sd.conf, by default only probes for SCSI devices with LUNs of 0 during system boot. If you attach storage arrays or other SCSI devices to your system that have a SCSI LUN other than 0, the device will not be seen by the operating system. If you are able to see the devices with the Open Boot Prompt probe-scsi-all command but not with the operating system's format command, then sd.conf likely has to be modified.
Here is example format output before sd.conf changes:

Note that only SCSI disks with a LUN of 0 are recognized by the operating system. The output of probe-scsi-all shows that I have SCSI disks with targets of 0, 1, 2, and 3, with LUNs of 0 through 6. I have to add these target/LUN combinations to sd.conf and perform a reconfiguration reboot, as the commands drvconfig;devlinks;disks do not appear to recognize these disks on a running system.
Additions to /kernel/drv/sd.conf:

Perform a reconfiguration reboot with reboot -- -rv or with boot -rv at the Open Boot Prompt.
Here is example format output after the sd.conf changes and a reconfiguration reboot:

Adding SCSI target/LUN combinations to sd.conf that are not available on your system should result in only a minor slowdown during boot, according to this
