For a scsi_device to support multipath, introduce structure
scsi_mpath_device to hold multipath-specific details.
Like NS structure for NVME, scsi_mpath_device holds the mpath_device
structure to device management and path selection.
Two module params are introduced to enable multipath:
- scsi_multipath
- scsi_multipath_always
SCSI multipath will only be available until the following conditions:
- scsi_multipath enabled and ALUA supported and unique ID available in
VPD page 83.
- scsi_multipath_always enabled and unique ID available in VPD page 83
Why don't you merge these two options, and have
scsi_multipath=on
and
scsi_multipath=always
?
Cheers,
Hannes
