Adding an Internal Disk Drive
Adding an Internal Disk Drive
1. Complete or modify the following forms for the installer:
•
Installation Document Checklist.
•
System Equipment Inventory Form. List only the disk drive that is being added
to the system.
•
System Enclosure Checklist. Show where in the enclosure the disk drive is to
be installed.
2. Install the disk drive as described in the installation part of the replacement
procedures on the NTL Support and Service Library. See Support and Service
Library on page 1-30.
3. Use SCF to add the disk drive to the system configuration database as described
in the SCF Reference Manual for the Storage Subsystem. You can configure your
system to do this automatically.
4. Test the new system configuration.
Changing the Configuration of a Disk Drive
You can change many of the configuration attributes of a disk drive, such as:
•
The logical device name of the disk volume (except for the $SYSTEM disk volume)
•
The alternate volume name of the disk volume
•
The cache size of the disk
•
Attributes related to the reviving half of a mirrored volume
All system configuration changes to a disk drive can be performed online. Refer to the
SCF Reference Manual for the Storage Subsystem for information about configuring
disk drives.
Online Disk Remirroring (ODR) is a new feature of storage subsystem management for
disks. ODR allows you to perform the following tasks without their having to stop the
entire disk volume:
•
Add a mirror disk drive to an unmirrored disk volume.
•
Delete a mirror disk drive from a mirrored disk volume.
•
Switch the roles between the primary and mirror disk drive of a mirrored disk
volume.
