Examples

Before setting the I/O delay on an array, use the container list

command to obtain information about any existing arrays.

As the following example shows, there is an array 0 (a volume set)

on this controller:

AAC0>container list

Executing: container list

Num Total Oth Stripe Scsi Partition

Dr Label Type Size Ctr Size Usage C:ID:L Offset:Size

-- ----- ------ ------ --- ------ ------- ------ -------------

F: 0 Volume 10.0MB NTFS 0:02:0 64.0KB: 10.0MB

The following example creates a mirror set asynchronously and sets

an I/O delay of 20 milliseconds for array 0. You need to perform the

create mirror task asynchronously. Otherwise, you cannot change

the I/O delay:

container create mirror /io_delay=20 0 (0,2,0)

Executing container create mirror /io_delay=20 0 (CHANNEL=0,ID=2,LUN=0)

The following example shows how to change the I/O delay to 40

milliseconds on the currently running create mirror task:

AAC0>container set io_delay 0 40

Executing: container set io_delay 0 40

Use the container list command after using the container

set io_delay

command to display information about the array,

as in the following example:

AAC0>container list

Executing: container list

Num Total Oth Stripe Scsi Partition

Dr Label Type Size Ctr Size Usage C:ID:L Offset:Size

-- ----- ------ ------ --- ------ ------- ------ -------------

F: 0 Volume 10.0MB NTFS 0:02:0 64.0KB: 10.0MB

As the example shows, there is no difference between the array list

display prior to and after the set I/O delay operation.
