Description 
Solaris 9
SAN 4.4
X6768 HBAs - latest firmware as of 3/05
MPxIO configured and working
STK-D280 array (engenio 2882) - both controllers active, and acting as failover controller for the other controller's luns
----------------------------

customer is experiencing hundreds of these messages on boot:

WARNING: /scsi_vhci/ssd@g600a0b800016525c00000045421c1e57 (ssd504):
Request Sense couldn't get sense data

WARNING: /scsi_vhci/ssd@g600a0b800016525c00000045421c1e57 (ssd504):
Request Sense couldn't get sense data

...

2 per secondary lun when the primary controller comes online.  This increases boot time on the order of 5-10 minutes per host since the secondary path to a failover lun will not return a corect read_capacity (opcode 0x25) for the "shadowed" volume.

STK-D280 array (Engenio 2882 controller) - which will also affect our SE6130 array (Engenio 5884 controller .. same firmware)

appears to be related to bugid 4850100, but should be fixed in the mpxio driver.
