Subject: [PATCH] udev-rules: set ctrl_loss_tmo to -1 for ONTAP NVMe/TCP
|
|
|
|
Setting ctrl_loss_tmo to -1 for ONTAP NVMe/TCP controllers would enable
|
|
indefinite reconnect attempts during a path loss and help avoid purging
|
|
the path on the host, which otherwise may lead to mounted fs read-only
|
|
behavior. So add a rule towards enabling the same.
|
