Diagnosing and Resolving Shared Disk Problems A-5 Run Disk Management On All Nodes Perform these steps from each node: 1. From Disk Management, verify that each RA4000 Array or RA4100 Array is visible. 2. Verify that all shared drive information (drive letters, volume labels, number of partitions, partition sizes, etc.) is consistent across all nodes. 3. Repeat steps 1 and 2 for all nodes in the cluster. Run and Validate the Array Configuration Utility On All Nodes The Array Configuration Utility is used to configure the hardware aspects of disk drives connected to the RA4000 Array Controllers. The Array Configuration Utility allows you to configure RAID levels and to add disk drives or RA4000/RA4100 Arrays to an existing configuration. Like Disk Management, it also provides each node with a detailed view of the shared storage resources in the cluster. To run and validate the Array Configuration Utility from each node, perform these steps: 1. From the Array Configuration Utility, verify that all RA4000/RA4100 Arrays and their logical disks are visible and consistent across all nodes. 2. Verify that each RA4000/RA4100 Array's serial number for all shared disks is consistent across all nodes. 3. Verify that the RAID configurations of RA4000/RA4100 Array shared disks are consistent across all nodes. 4. Repeat steps 1 through 3 for all nodes in the cluster.

Diagnosing and Resolving Shared Disk Problems
A-5
Run Disk Management On All Nodes
Perform these steps from each node:
1.
From Disk Management, verify that each RA4000 Array or RA4100
Array is visible.
2.
Verify that all shared drive information (drive letters, volume labels,
number of partitions, partition sizes, etc.) is consistent across all nodes.
3.
Repeat steps 1 and 2 for all nodes in the cluster.
Run and Validate the Array Configuration
Utility On All Nodes
The Array Configuration Utility is used to configure the hardware aspects of
disk drives connected to the RA4000 Array Controllers. The Array
Configuration Utility allows you to configure RAID levels and to add disk
drives or RA4000/RA4100 Arrays to an existing configuration. Like Disk
Management, it also provides each node with a detailed view of the shared
storage resources in the cluster.
To run and validate the Array Configuration Utility from each node, perform
these steps:
1.
From the Array Configuration Utility, verify that all RA4000/RA4100
Arrays and their logical disks are visible and consistent across all nodes.
2.
Verify that each RA4000/RA4100 Array’s serial number for all shared
disks is consistent across all nodes.
3.
Verify that the RAID configurations of RA4000/RA4100 Array shared
disks are consistent across all nodes.
4.
Repeat steps 1 through 3 for all nodes in the cluster.
