Incorrect fabric WWN and path_to_inst Solaris 9


Over a period of time we gradually migrated all LUN's from our HP EVA array over to our EMC array. From the server it would appear some files require a tidy up and was wondering what the impact it would have if changes were to be made to the fabric_WWN_map and path_to_inst files and if there is a correct procedure in doing this.

The fabric_WWN_map file is still configured with entries to the HP array.

/devices/pci@9,600000/SUNW,qlc@1/fp@0,0:fc::50001fe15000de38 HP
/devices/pci@9,600000/SUNW,qlc@1/fp@0,0:fc::500601633b202f83 EMC
/devices/pci@9,600000/SUNW,qlc@2/fp@0,0:fc::50001fe15000de38 HP
/devices/pci@9,600000/SUNW,qlc@2/fp@0,0:fc::5006016b3b202f83 EMC

The path_to_inst file still has the following entries

"/pci@9,600000/SUNW,qlc@1/fp@0,0/ssd@w50001fe15000de39,2d" 4523 "ssd"

Is it safe to manually remove these entries? There is no device files in /dev/dsk

The path_to_inst also contains the following

"/scsi_vhci/ssd@g600508b400074464000100000a620000" 422 "ssd"
"/scsi_vhci/ssd@g600508b400074464000100000a790000" 423 "ssd"
"/scsi_vhci/ssd@g600508b400074464000100000a7d0000" 424 "ssd"
"/scsi_vhci/ssd@g600508b400074464000100000a810000" 425 "ssd"
"/scsi_vhci/ssd@g600508b400074464000100000a920000" 426 "ssd"
"/scsi_vhci/ssd@g600508b400074464000100000a960000" 427 "ssd"
"/scsi_vhci/ssd@g600508b400074464000100000a9a0000" 428 "ssd"
"/scsi_vhci/ssd@g600508b400074464000100000aab0000" 429 "ssd"
"/scsi_vhci/ssd@g600508b400074464000100000aaf0000" 430 "ssd"
"/scsi_vhci/ssd@g600508b400074464000100000ab30000" 431 "ssd"

What are these and can they be removed?

All other configuration looks ok, there are no old occupants for the HP array.
