General Operating Guidelines and Limitations

 

 

Operating System /

 

Affected Component

Description

 

 

All

Be aware of the following limitations regarding file systems and stripe

 

groups:

 

• The maximum number of disks per file system is 512

 

• The maximum number of disks per data stripe group is 128

 

• The maximum number of stripe groups per file system is 256

 

• The maximum number of tape drives is 256

 

 

 

To prevent data loss and aid disaster recovery, Quantum recommends

 

adjusting policy settings to retain two copies of critical data. In addition, data

 

stored to a storage disk should be stored on RAID (or, if only one copy is

 

retained, the RAID should be mirrored). This way, in the event of a disk

 

failure, no data is lost.

 

 

 

The trashcan feature has been removed in StorNext 3.0. Before upgrading to

 

StorNext 3.0, you must empty the trashcan on all file systems where this

 

feature is enabled. If the trashcan directories are not removed, the upgrade

 

will fail.

 

To empty the trashcan on a file system where it is enabled, change to the file

 

system directory (for example /stornext/snfs1). Then, at the command

 

prompt, type:

 

rm -rf TrashCan

 

Repeat this procedure for all file systems.

 

 

 

StorNext File System is incompatible with third-party portmappers.

 

 

 

Hot re-zoning of SAN fabrics is not supported.

 

 

 

Affinity names cannot be longer than eight characters. StorNext truncates

 

affinity names after the eighth character, so if you have two or more affinities

 

whose first eight characters are identical, StorNext considers them the same

 

affinity. For example, if you have affinities called “affdata01” and

 

“affdata02,” StorNext sees them both as “affdata0” and treats them as the

 

same affinity.

 

 

 

For managed file systems only, the maximum directory capacity is 50,000

 

files per single directory. (This limitation does not apply to unmanaged file

 

systems.)
