Repair Storage Pools Instead of Individual Volumes

Mirror Partitions

You can specify no Hot Fix Redirection Area when you create disk partitions.
Having no Hot Fix Redirection Area saves partition space. This might be
useful on large RAID systems that provide a method of fault tolerance.
IMPORTANT:
If Hot Fix is not enabled, then the partition will not have the fault
tolerance provided by NetWare. Data on corrupted sectors of the disk won't be
redirected to the Hot Fix Redirection Area. In addition, you cannot mirror partitions
that do not use Hot Fix. It is easiest to enable Hot Fix when you create the partition.
To add Hot Fix later, you must delete all the volumes on the partition.
You use VREPAIR to fix traditional volumes. For instructions on using
VREPAIR, see VREPAIRUtilities
repair utilities called VERIFY and REBUILD on the storage pools that
contain the logical volumes. For instructions on rebuilding logical volumes,
see "Rebuilding NSS Storage Pools and Volumes" on page
VERIFY checks the file system integrity for an NSS pool by searching for
inconsistent data blocks or other errors. This utility indicates if there are
problems with the file system.
REBUILD verifies and uses the existing leaves of an object tree to rebuild all
the other trees in the system. You need to deactivate pools (and all the volumes
in the pools) before you run Rebuild so users cannot access the volumes you
are rebuilding.When you deactivate a storage pool, all the volumes in the pool
automatically deactivate.
These utilities are not the same as VREPAIR. You should use REBUILD only
as a last resort to recover the file system after data corruption. When you use
REBUILD and VERIFY, a log file is generated to the root of the DOS drive.
You can protect your data by mirroring your partitions. Mirroring stores the
same data on separate disks using the same controller channel. Using
ConsoleOne, you can mirror both traditional and NSS partitions.
The following is a list of requirements for mirroring partitions:
Mirrored partitions must have the same partition type as you mirror the
partition to. In other words, you can only mirror NSS partitions to other
NSS partitions—the same applies to traditional partitions.
Reference. For logical volumes, you use
48.
