Quiesce I/O on a path to array
Availability: This command is available to cluster administrators at the admin privilege level.
Description
The storage path quiesce command quiesces I/O on one path to a LUN. It also quiesces the given entire path immediately or can monitor the given path for error threshold before quiesce. After the I/O has been quiesced, no new I/O is sent on the path unless the storage path resume command is issued to continue I/O.
Parameters
-node {<nodename>|local}- Node name-
The name of the clustered node for which information is being displayed.
-initiator <initiator name>- Initiator Port-
Initiator port that the clustered node uses.
-target-wwpn <wwpn name>- Target Port-
Target World Wide Port Name. Port on the storage array that is being used.
- {
[-lun-number <integer>]- LUN Number -
Logical Unit number. The range is: [0…65535]. If this parameter is not specified, ONTAP resumes the entire path to an array.
- |
[-path-failure-threshold <integer>]- Max Number of Path Failures Acceptable During wait-duration -
The path failure count, exceeding this value within wait duration will quiesce the path.
[-wait-duration <integer>]- Wait Duration in minutes }-
The time duration(minutes) in which path is monitored for path failures.
Examples
The following example suspends I/O between node vbv3170f1b, port 0a and the array port 50001fe1500a8669, LUN 1.
node::> storage path quiesce -node vbv3170f1b -initiator 0a -target-wwpn 50001fe1500a8669 -lun-number 1
The following example suspends I/O immediately between node vbv3170f1b, port 0a and the array port 50001fe1500a8669.
node::> storage path quiesce -node vbv3170f1b -initiator 0a -target-wwpn 50001fe1500a8669
The following example suspends I/O between node vbv3170f1b, port 0a and the array port 50001fe1500a8669 after reaching 10 or more errors in duration of 5 mins.
node::> storage path quiesce -node vbv3170f1b -initiator 0a -target-wwpn 50001fe1500a8669 -path-failure-threshold 10 -wait-duration 5
