Bug description:
Request to include patch set "PATCH 00/14] mpt3sas: Add support for
multi-port path topology" which will support the topologies where
zoning is enabled in the expander as shown below,
Zone 1 Zone 2
|-----------------| |----------------|
| HD1 ..... HD25 | | HD26 ......HD50|
| |==================================| |
| | | | | |
| | Expander | |
| |==================================| |
| | | | | |
|-----------|-----| |----|-----------|
x8| |x8
_______|______________|_______
| HBA |
|____________________________|
Current driver doesn't support this type of topology and will add only one
zoned drives to the OS. So to support these types of topology we need below
patch set in the driver.
https://marc.info/?l=linux-scsi&m=160226366707807&w=2
So, requesting you include this patch for next upcoming Ubuntu kernel
release.
Currently we have posted this patch set to upstream community and they
yet to review this patch set. Meanwhile If I get the base kernel
source code for next upcoming Ubuntu kernel then I can prepare the
patches over this base kernel source and share it in this BZ.
Thanks,
Sreekanth
