Subject: [PATCH] multipathd: checker port_state before setting it.
|
||||
|
||||
If the rport port_state is already Marginal, trying to set it to
|
||||
Marginal causes an error like the following:
|
||||
|
||||
multipathd[365376]: /sys/devices/pci0000:c0/0000:c0:01.1/0000:c4:00.0/host0/rport-0:0-5/fc_remote_ports/rport-0:0-5: failed to set port_state to marginal: Invalid argument
|
||||
|
||||
To avoid causing this confusing error message, check if the port_state
|
||||
is already marginal before trying to set it.
