Switches

/wait{=boolean}

Specifies whether to create the mirror set synchronously. If

you set this switch to TRUE, the command prompt does not

return until the mirror-set creation completes. If you set this

switch to FALSE, the mirror-set creation starts asynchronously

and the command prompt returns immediately.

/io_delay{=integer}

Specifies the number of milliseconds the controller waits

between the I/Os required to create the mirror set. If you do

not specify this switch, the I/O delay is always zero (0). The

I/O delay value is not preserved between reboots of the

operating system.

Examples

Before creating a mirror set, use the container list command

to obtain information about any existing arrays. As the following

example shows, there is one existing array (array 0, a volume set) on

this controller prior to the time the mirror set is created:

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 10MB NTFS 0:02:0 64.0KB: 10.0MB

The following example shows how to create a mirror set

synchronously from volume set 0 using freespace on SCSI device

(0,3,0):

AAC0>container create mirror /wait /io_delay=10 0

(0,3,0)

Executing: container create mirror /wait=TRUE

/io_delay=10 0

(CHANNEL=0, ID=3,LUN=0)

As the command executes, note the title bar of the DOS window

displays the status of the command. For example:

Stat:OK!Task:101,Func:MCR Ctr:0,State:RUN 97.2%

1 2 ... 49 50 51 52 53 54 55 56 57 58 59 ... 353 354
