Cluster Management 6-15 Adding Disk Drives to Increase Storage Capacity During the life of your PDC/O2000 cluster, you might need to expand the capacity of an RA4000 Array or RA4100 Array. The following steps describe how to add drives to an RA4000/RA4100 Array and how to allocate the added disk capacity to Oracle. The drive can be added and allocated to Windows 2000 Advanced Server while the database is online. The following summarizes the procedure. 1. Physically add the drives to the RA4000/RA4100 Array. 2. On the primary node, run the Array Configuration Utility to create drive arrays, configured with RAID, and then create logical drives. 3. Using Disk Management, create an extended partition on each of the logical drives. 4. Using Disk Management, create logical partitions within each extended partition. IMPORTANT: Do not format the drives. Oracle Parallel Server uses raw partitions, which requires that the drive not be formatted with any file system. 5. Verify that the same shared disk resources are seen from every node in the cluster by running Disk Management on each node. 6. Make sure you can see the same shared disk resources from each node using Secure Path Manager as you can using the Disk Management. 7. Perform the necessary Oracle commands to associate the new data files to the database. Refer to the Oracle8i Parallel Server Setup and Configuration Guide for more detailed instructions. Adding an RA4000/RA4100 Array You must shut down the cluster to add an RA4000/RA4100 Array. The following steps summarize the procedure: 1. Shut down the Oracle instance on each cluster node. 2. Stop the Oracle services running on each node. 3. Shut down Windows 2000 Advanced Server on each node and power off all the cluster nodes. 4. Power off all of the RA4000/RA4100 Arrays.

Cluster Management
6-15
Adding Disk Drives to Increase Storage Capacity
During the life of your PDC/
O
2000 cluster, you might need to expand the
capacity of an RA4000 Array or RA4100 Array. The following steps describe
how to add drives to an RA4000/RA4100 Array and how to allocate the added
disk capacity to Oracle.
The drive can be added and allocated to Windows 2000 Advanced Server
while the database is online. The following summarizes the procedure.
1.
Physically add the drives to the RA4000/RA4100 Array.
2.
On the primary node, run the Array Configuration Utility to create drive
arrays, configured with RAID, and then create logical drives.
3.
Using Disk Management, create an extended partition on each of the
logical drives.
4.
Using Disk Management, create logical partitions within each extended
partition.
IMPORTANT:
Do not format the drives. Oracle
Parallel Server uses raw partitions, which
requires that the drive not be formatted with any file system.
5.
Verify that the same shared disk resources are seen from every node in
the cluster by running Disk Management on each node.
6.
Make sure you can see the same shared disk resources from each node
using Secure Path Manager as you can using the Disk Management.
7.
Perform the necessary Oracle commands to associate the new data files
to the database.
Refer to the
Oracle8i Parallel Server Setup and Configuration Guide
for more
detailed instructions.
Adding an RA4000/RA4100 Array
You must shut down the cluster to add an RA4000/RA4100 Array. The
following steps summarize the procedure:
1.
Shut down the Oracle instance on each cluster node.
2.
Stop the Oracle services running on each node.
3.
Shut down Windows 2000 Advanced Server on each node and power
off all the cluster nodes.
4.
Power off all of the RA4000/RA4100 Arrays.
