Description

QDepth

Number of Read/Write commands that can be queued to the external volume. The numbers 2 through 128 can be entered. When two or more external paths with different values are selected, the field is blank.

When Load Balance Mode is Extended Round-robin and the I/Os issued to the external volume are sequential, the number of Read/Write commands that can be queued at one time is the total of the QDepth values of all the external paths.

I/O Timeout

Number of seconds that should pass before I/O to the external volume times out. The numbers 5 through 240 can be entered. When two or more external paths with different values are selected, the field is blank.

Blocked Path Monitoring

Time that elapses from the time that a path goes down to the time when the external volume is blocked. The numbers 5 through 180 can be entered. When two or more external paths with different values are selected, the field is blank.

Caution

If you want to change multiple parameters for an external WWN more than once, wait until the currently applied task finishes, and then perform the next setting change.

If you make a setting change for the next task before completing the last, the setting will be applied to the next task only. The result might be different from what you expected.
