/*****************************************************************
init_cciss_to_bmic()
There are two ways of addressing logical drives, and it depends what
you're doing which way you have to use. Generally, SCSI things,
like reads, writes, inquiries, etc. use the 8-byte LUN as reported by
REPORT_LOGICAL_LUNS. And BMIC commands use another way, I'll call
it "the BMIC way."
There can be controllers behind controllers. For instance, you might
have a 6400 HBA cabled to a MSA500 external box. The 6400's a smartarray
PCI board connected via SCSI cables to the MSA500. The MSA500 has a
Smartarray RAID controller inside it. The controller in the MSA500 will
have an 8-byte LUN address, as does the 6400. The 6400's LUN will be all
zeroes. The MSA500's will be something else, as reported by REPORT_PHYSICAL_LUNS,
and identified as an MSA500 by an inquiry to that LUN.
Further complications can come up with SSP, in that there may be logical
drives addressable the "BMIC way", which are not addressable via any
8-byte LUN from the host. (more of a SAN thing, but anyhow...)
So, an address of a logical drive "the BMIC way" consists of the LUN of
the controller which that logical drive is on, plus a "BMIC drive number"
which gets crammed into the BMIC CDB.
So, how do you figure out the BMIC address which corresponds to a given
8-byte lun address? For specific controllers, there may be some shortcuts.
However, to do it in a general way, without having to be aware of nasty
controller details nobody should be forced to be aware of, the following
algorithm is implemented.
Do a report logical LUNs to get a list of LUNs. (On some controllers
which support a large number of logical drives, this may take
awhile to complete.)
Get inquiry page 0x83 from each LUN which supports it,
and remember this data.
Do a report physical LUNs, and an inquiry to each to find
any external RAID controllers (e.g. MSA500).
For each controller (LUN 0x0000000000000000 plus any external
controllers found in previous step) do:
BMIC 0x10, identify logical drive.
This returns, among other things, same data as inquiry page 0x83, above.
Match up the data returned by BMIC 0x10 with Inquiry page 0x83.
init_cciss_to_bmic implements this algorithm.
You might wonder why instead, we don't just have for example vendor specific
inquiry pages accessible via the 8-byte LUN which report the same things
as are accessible via the old "BMIC way", esp, e.g. SENSE_LOGICAL_DRIVE_STATUS.
I wonder the same thing myself.
This function has the side effect of filling out controller_lun_list[]
and num_controllers.
