To create a RAID5 array, go to the Logical View
and select the RAID5 Resource List. Then click
"Create Array". You will be presented with a form as shown here :
Creating a System (PC) RAID 5 Resource
|
Enter the name you wish to give your new array ( Your R5 Name ), the number of components it will contain, and change any of the attributes as you require. Then click either "Cancel" to quit, "OK" to proceed and select which resources will become part of the array, or click "Auto" to automatically create the array. "Auto" asks the adapter to pick the first n (where n is the number of components) applicable components to create the array from. For this example we assume you selected "OK".
After clicking "OK" you are presented with the following form:
On this page you select which free resources you wish to use to create your array. This form shows the first three resources selected. Note that although two of these resources are 18Gb, the array will only use the first 9.1Gb of these resources as the second component is only 9.1Gb. Also remember that with IBM SerialRAID Adapter, components of an array must all reside on the same SSA loop, i.e. SIC A or SIC B.
Selecting "Create" will create this array and return you to the RAID 5 Resource List where you will see the new array (its "usage" will be shown as "free"). "Cancel" will return you to the RAID 5 Resource List without creating the array.
You should now see your new array in the Resource List as shown below, and it should start rebuilding the parity data (if it is a RAID 5 array).
You now want to make this resource available to your operating system. To do this,
select the array name link, to access the Resource
View page as shown here:
From this page you can perform various array maintenance and configuration tasks,
such as modifying the attributes, or making the array a Fast Write resource. We wish to
make it available to the operating system, so we select "Attach" and are presented
with the following page:
This page is prompting you for a "Resource Number". This number defines where this resource will be placed in the list of resources presented to the operating system (01h, 02h, 03h, etc.). This is important if you are booting off of an SSA resource, or if you have drive letter constraints. See the documentation supplied with your adapter for more information.
Here we select 08h and click "Attach". We are then returned to the Resource List page, where you can see that your array "usage" has changed from free (blue) to system (PC) (green).
From the Logical View, select the RAID 5
Resource List page, then select the RAID 5 array
created above ("Your R5 Name" in this example).
You will be shown the Resource View page, as
shown above.
Select "Create FW" and your RAID 5 array will be modified to be a Fast Write
RAID 5 array.
N.B. : Fast Write is only supported in a 1-way loop, and on the IBM SerialRAID Adapter
To create a System (PC) Non-RAID resource, go to the
Logical View and select the Free Non-RAID Disk
Resource List. You will see a page similar to this:
Making this array a Fast Write resource
Creating a System (PC) Non-RAID Disk
Click on the serial number of the resource you wish to make available to the operating system. This will display the Resource View for that resource :
Click "Attach" and you will be presented with the Attach page, where you must enter the resource number you wish to assign to this resource.
When you click "Attach" on the Attach page, you will be returned to the Free Non-RAID Disk Resource List. Click on the Back arrow in the navigation area to view the Logical View where you can confirm that the resource you attached is now a member of the System (PC) Resource List.
To create a Hot Spare Non-RAID resource, go to the
Logical View and select the Hot Spare
Non-RAID Disk Resource List.
You will see a page similar to this:
Creating a Hot Spare Non-RAID Disk
Selecting "Create Hot-spare" will display the Hot-spare attributes page, where you can select the Block size for this Hot-spare. Note that this must correspond to the Block size of the array for which this hot-spare is intended!
Click "OK" when you have entered the Block size.
After selecting "OK", you will be given a list of Free resources. Select the resource you wish to make a Hot-spare, remembering that it must be in the same SSA loop as the array it is for. Note that arrays with a "usage" of Free are also candidates to be made Hot-spare, i.e. you can have an entire Hot-spare array :
Select the resource you wish to make a Hot-spare and click "Create". You will be returned to the Hot-spare Resource List where your new Hot-spare resource will be listed.
