ps-manual-failover-exp.patch - this is just an exmaple of how you
could use
the init function. Please do not apply it. It was written based on
some other
patches, and I am trying to make it more generic so we can support
other HW.
I am only sending it becuase I am not sure if the functions I am using to
send the failover command are correct and I am looking for feedback.
For the failover command I am currently hardcoding the format in the
path-selector.
This seems like such a waste becuase if you look at sg io code
(block/scsi_ioctl.c
for example), you can just pass in the command you want to execute. Is
there any way
I could pass in such a thing when my target is created, so that way dm
multipath
would not have any type of command format functions/modules or definitions
(it could just be passed in and built like the sg io code).
Wait let me clarify. I would not be using the sgio code. It would just
work similar to that code. I really just don't want to be forced to
have a bunch of different commands for different devices defined in a
kernel module. Christophe's tool can already determine the storage
device and the proper type of failover model to use, so when it creates
a device that requires manaul failover it can pass dm-multipath the
command too.
