Enabling Disk Mirroring

This procedure is intended primarily for customers who have purchased the Avaya IR software-only solution and want to enable Disk Mirroring for their Sun Fire 280R or Sun Fire V240 systems. It can also be used by customers who are recovering from a catastrophic situation in which they find it necessary to re-install all system software.

To enable Disk Mirroring:

1. Verify that your system is partitioned correctly (for disk partitioning requirements see Disk Mirroring feature). If it is not, you must either:
   • Repartition your system to meet these disk partitioning requirements; or
   • Use the Sun DiskSuite 4.2.1 tools to manually enable Disk Mirroring for your system (for more information, see Sun DiskSuite commands used for Disk Mirroring).
2. If you are not logged in, log in as root.
3. Install the Avaya IR software, which copies the Disk Mirroring package (AVdm) to the /exports/optional_features directory.
4. To verify that the Sun DiskSuite 4.2.1 tool package is installed on your system, enter pkginfo -l | grep -i suite
5. To move to the optional_features directory, enter cd /export/optional_features
6. To install the Disk Mirroring package, enter pkgadd -d . AVdm
7. Run mirror_admin setup.
8. Reboot the system.

   If the system is partitioned correctly, then rebooting the system automatically starts synchronizing the two disks. It takes approximately 20 minutes for each 10 GB to copy data to the secondary (mirrored) hard disk.
