Working with FCP devices for the first time.
I have 2 devices that I am using to multipath.
I've followed the manual pretty well to multipath these devices.
multipath -ll
multipathd -k'show topo'
is preferred because
- it only works if multipathd runs which is a requirement
- it does not cause unnecessary load due to extra path checks
36005076307ffd4da0000000000000028 dm-1 IBM,2107900
size=100G features='1 queue_if_no_path' hwhandler='0' wp=rw
`-+- policy='service-time 0' prio=1 status=active
|- 0:0:0:1076379648 sda 8:0 active ready running
`- 1:0:0:1076379648 sdb 8:16 active ready running
So now I have this device with the really long name -
/dev/mapper/36005076307ffd4da0000000000000028
/dev/mapper/36005076307ffd4da0000000000000028_part1
In the manual it talks about using udev to map it to a more friendly name,
there it goes wrong. The manual talks about udevinfo, which doesn't exist,
it's part of udevadm, but that output doesn't look like the manual.
I'm looking for example of udevadm to add a rule to rename those to
something short and easy to remember.
Which manual do you refer to?
While udev can be used in general to rename devices,
for multipath devices there is a much easier common way to do this via
alias names in multipath.conf:
