Editing RAID Cards (section)

== Creating/removing mirror ==
=== via CLI ===

First, you have to make sure the new disk(s) is/are wiped clean – '''a disk with containers from another system will crash the system when inserted'''. You can do this initializing the drive(s) in another system.

Get into the CLI, rescan the controller:
 AAC0> controller rescan
to get it to find the newly inserted disks

<pre>AAC0> container list
Executing: container list
Num          Total  Oth Chunk          Scsi   Partition
Label Type   Size   Ctr Size   Usage   B:ID:L Offset:Size

 /dev/sda                              0:01:0 64.0KB:68.3GB

AAC0> disk list
Executing: disk list

0:03:0   Disk            143374738 512         Initialized      NO     160</pre>

if the disks aren’t initialized:
<pre>AAC0> disk initialize (0,2,0) 
AAC0> disk initialize (0,3,0)
AAC0> disk show space
Executing: disk show space

Scsi B:ID:L Usage      Size
----------- ---------- -------------
  0:00:0     Container 64.0KB:68.3GB
  0:00:0     Free      68.3GB:7.50KB
  0:01:0     Container 64.0KB:68.3GB
  0:01:0     Free      68.3GB:7.50KB
</pre>

Finally, create the mirror:
<pre>AAC0> container create volume /label=MIRROR1 ((0,2,0))
Executing: container create volume /label="MIRROR1" (BUS=0,ID=2,LUN=0)
Container 1 created at /dev/sdb

AAC0> container list
Executing: container list
Num          Total  Oth Chunk          Scsi   Partition
Label Type   Size   Ctr Size   Usage   B:ID:L Offset:Size
----- ------ ------ --- ------ ------- ------ -------------

 /dev/sda                              0:01:0 64.0KB:68.3GB

 1    Volume 8.47GB            Valid   0:02:0 64.0KB:8.47GB
 /dev/sdb             MIRROR1

Create volume on 1 of to disks to be in mirror (fdisk, format),
Then to mirror:

AAC0> container create mirror 1 (0,3,0)
Executing: container create mirror 1 (BUS=0,ID=3,LUN=0)

AAC0> container list
Executing: container list

 1    Mirror 8.47GB            Valid   0:02:0 64.0KB:8.47GB
 /dev/sdb             MIRROR1          0:03:0 64.0KB:8.47GB

AAC0> task list
Executing: task list

To remove:
MAKE SURE DRIVE NOT MOUNTED FIRST!

Example: delete 2nd mirror installed in slots 2-3

<pre>AAC0> container delete 1
Executing: container delete 1

AAC0> container list

 /dev/sda                              0:01:0 64.0KB:68.3GB


AAC0> enclosure prepare slot 0 2
Executing: enclosure prepare slot     0 2
AAC0> enclosure prepare slot 0 3
Executing: enclosure prepare slot     0 3</pre>

You may now remove drives

To create mirrors from a volume (see next section where we add drives as volume)

<pre>CLI > open aac0

If this happens:

<pre>AAC0> container create mirror 1 (0:3:0)
Executing: container create mirror 1 (BUS=0,ID=3,LUN=0)
Command Error: <The controller was not able to mirror the specified container.>

AAC0> disk initialize /always (0,3,0)
Executing: disk initialize /always=TRUE (BUS=0,ID=3,LUN=0)</pre>

Then:

<pre>AAC0> container create mirror 1 (0:3:0)
Executing: container create mirror 1 (BUS=0,ID=3,LUN=0)</pre>

In the case of a drive that won't remirror due to a Mirror Failover Container 0 no failover assigned:

 container set failover 0 (0,0,0) 
where 0,0,0 is the new empty drive

=== via BIOS configuration utility ===

Press Ctrl-A to enter the configuration utility while the Adaptec BIOS is booting.

<pre>Container configuration utility->
Initialize drives->(ins to select all drives you wish to use- DO NOT CHOOSE DRIVES IN USE IN EXISTING ARRAY)
Create container->
(Select the newly-initialized drives)
Container type: RAID1
Container label: MIRROR0
(confirm correct size)
Read caching: Y
Write caching: enable when protected
(done)
</pre>

Repeat the process if you're building another mirror. Call it MIRROR1

Procedure for setting two, ½ mirrors (two volumes) which you can later convert to two mirrors:
<pre>Create array->
(Select 1st drive)
(enter)
Container type: Volume
Container label: MIRROR0
(confirm correct size)
Read caching: Y
Write caching: enable always
(answer y to both warnings)
(done)

Create array->
(Select 3rd drive)
Container type: Volume
Container label: MIRROR1
(confirm correct size)
Read caching: Y
Write caching: enable always
(answer y to both warnings)
(done)

(exit util)</pre>

To remove a drive:

Go to the "Manage Arrays" screen, move the cursor over the mirror you want to delete and press the delete key.
