Changing an unmanaged array to a managed array

Sites that perform an upgrade from SPM 1.x to SPM 2.x may end up with an unmanaged array

representing some of their storage resources. If this cannot be resolved by performing the upgrade

a second time, it may be necessary to manually transition these storage resources from an

unmanaged array to a managed array. Alternately, sites that have chosen to represent some arrays

as unmanaged arrays may decide to make them managed at a later date. In either case, the

following steps must be performed.

1. Note active services using the unmanaged array, the volume associated with each service,

and the deactivation policy for each service.

2. For each service, change the deactivation policy to “No Action”.

3. Deactivate each service.

4. Remove the unmanaged array from SPM.

5. Import the managed array into SPM, along with any pools and volumes that will be needed

to replace the volumes used by the services in step 1.

6. Activate each service, choosing the proper volume from the managed array for that service.

7. For each service, reset the deactivation policy to its original value.

Example of an unmanaged array XML file

Following is an example of an XML file representing an unmanaged array. The example is provided

in Courier font. Annotations are provided within the example as normal font.

<?xml version="1.0" encoding="utf-8"?>

<StorageArrayDefinition xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:xsd="http://www.w3.org/2001/XMLSchema">

Every XML document must begin with the XML element indicating the XML version and the character

encoding. Every Unmanaged Array XML file must begin with the StorageArrayDefinition root

element. This example specifies two namespaces for use within this XML file, one for the

XMLSchema-instance schema, and a second for the schema schema.

</MapItem>

<Value>Normal</Value>

</MapItem>

</HostmodeMap>

This HostmodeMap element specifies that SPM's HPUX host mode maps to the host mode known

as HP-UX on the storage array, and that all other host modes known to SPM map to the Normal

mode on the storage array.

</MapItem>

</MapItem>

</MapItem>

</RAIDMap>

This RAIDMap element specifies that the RAID level known to SPM as RAID0 is known by the

storage array as RL0, and similarly for RAID levels 1 and 5. This implies that this device does not

support RAID levels NoRaid, RAID0, RAID3, RAID4, RAID6, RAID50, or RAID60. The
