Affected Component

Description

 

 

HA configurations

In HA (high availability) configurations, do not run adic_control start on the

 

standby server. Doing so may start StorNext Storage Manager components

 

on the standby server which are already running on the primary server, and

 

may result in database corruption.

 

 

IRIX

As of release 3.0, StorNext does not support metadata controllers running the

 

SGI IRIX operating system. To upgrade to StorNext 3.0 or higher, MDCs

 

running IRIX must be converted to a supported operating system. This

 

conversion must be performed by Quantum Professional Services. For more

 

information, or to schedule an IRIX conversion, contact Quantum Global

 

Services (see Quantum Technical Assistance Center on page 322).

 

NOTE: The StorNext 3.1.2 client software continues to support IRIX.

 

 

 

SNFS uses 64-bit inode numbers. 32-bit applications (programs compiled

 

without 64-bit) support may experience problems working with files with

 

inode numbers greater than 2147483648. 32-bit applications may also

 

encounter problems when dealing with files greater than 2TB in size, This

 

issue is not unique to StorNext, but may be encountered by some legacy

 

applications when working with SNFS on IRIX.

 

 

 

StorNext supports only SGI 64-bit versions of IRIX on operating systems that

 

use the SGI version of the QLogic QLA2200 or QLA2310 FC-HBAs.

 

 

 

On many versions of IRIX, the root crontab contains the following entry which

 

is used to remove old application crash dumps and temporary mail files:

 

find / -local -type f '(' -name core -o -name dead.letter ')' -atime +7 -mtime +7 -exec rm

 

-f '{}' ';'

 

If StorNext file systems are mounted, they will be traversed by this find

 

command which can have a dramatic impact on the performance of other

 

applications currently using these file systems. To prevent the traversal of

 

StorNext file systems, modify the find command so it reads:

 

find / -local '(' -type d -fstype cvfs -prune ')' -o -type f '(' -name core -o -name

 

dead.letter ')' -atime +7 -mtime +7 -exec rm -f '{}' ';'
