Cluster Management 6-15 The removal of a drive in an RA4000 Array or RA4100 Array must follow certain rules are that interpreted by reading the LEDs on the disk drive. Before proceeding, locate the information in the Compaq StorageWorks RAID Array 4000 User Guide or the Compaq StorageWorks RAID Array 4100 User Guide that describes the conditions under which a drive can be removed. Once you have determined it is safe to remove the drive, open both latches on the drive tray and remove the drive from the drive bay. Put the replacement drive into the drive bay and snap the latches in place. CAUTION: Failure to follow the rules described in the Compaq StorageWorks RAID Array 4000 User Guide or the Compaq StorageWorks RAID Array 4100 User Guide can result in loss of data. Adding Disk Drives to Increase Shared Storage Capacity During the life of your PDC/O1000 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. 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.

The removal of a drive in an RA4000 Array or RA4100 Array must follow
certain rules are that interpreted by reading the LEDs on the disk drive. Before
proceeding, locate the information in the
Compaq StorageWorks RAID
Array 4000 User Guide
or the
Compaq StorageWorks RAID Array 4100 User
Guide
that describes the conditions under which a drive can be removed. Once
you have determined it is safe to remove the drive, open both latches on the
drive tray and remove the drive from the drive bay. Put the replacement drive
into the drive bay and snap the latches in place.
CAUTION:
Failure to follow the rules described in the
Compaq StorageWorks
RAID Array 4000 User Guide
or the
Compaq StorageWorks RAID Array 4100 User
Guide
can result in loss of data.
Adding Disk Drives to Increase Shared Storage
Capacity
During the life of your PDC/O1000 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.
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.
