On both sparcv9 and x64 for snv_83 and snv_84, running "stmsboot -L" on an
mpxio-enabled system will fail to print out the device path to scsi_vhci path
mappings. The stmsboot command will still return 0/success.
Running "stmsboot -Lg" still works.
Almost definitely a problem for S10 Update 6 as well.
