Recovering from Removing the Wrong Physical Disk
If the physical disk that you mistakenly removed is part of a redundant virtual
disk that also has a hot spare, then the virtual disk rebuilds automatically
either immediately or when a write request is made. After the rebuild has
completed, the virtual disk no longer has a hot spare since data has been
rebuilt onto the disk previously assigned as a hot spare. In this case, you
should assign a new hot spare.
If the physical disk that you removed is part of a redundant virtual disk that
does not have a hot spare, then replace the physical disk and do a rebuild.
For information on rebuilding physical disks and assigning hot spares, see the
following sections:
• Understanding Hot Spares for RAID controllers
You can avoid removing the wrong physical disk by blinking the LED display
on the physical disk that you intend to remove. For information on blinking
the LED display, see
Blink and Unblink (Physical Disk) .
Resolving Microsoft Windows Upgrade Problems
If you upgrade the Microsoft Windows operating system on a server, you may
find that Storage Management no longer functions after the upgrade. The
installation process installs files and makes registry entries on the server that
are specific to the operating system. For this reason, changing the operating
system can disable Storage Management.
To avoid this problem, you should uninstall Storage Management before
upgrading. If you have already upgraded without uninstalling Storage
Management, however, you should uninstall Storage Management after the
upgrade.
After you have uninstalled Storage Management and completed the upgrade,
reinstall Storage Management using the Storage Management install media.
