Symptoms
After new LUNs are mapped from a StorEdge 9910 or 9960 from the SVP or Remote Console, the Solaris[TM]host does not recognize the new devices, even after editing sd.conf.

Resolution
When LUNs are mapped on the Hitachi 9910 or 9960, LUN assignments are done by associating a LUN number with a particular LDEV ID.

The LUN number that is assigned by the subsystem is hex. The sd driver in Solaris however identifies LUNs by their decimal address - LUN definitions in hex will be ignored . Therefore, any LUN number above 09 needs to be translated to decimal in order to be correctly identified by the sd driver in /kernel/drv/sd.conf.

For example:

/devices/pci@1,4000/fibre-channel@4/sd@4, a

would translate to the following sd.conf entry:

name="sd" class="scsi" target=4 lun= 10

Please note that a reconfiguration boot is required to make any changes in /kernel/drv/sd.conf effective.
