Quantum 3.5.2 manual Operating System Affected Component Description, Irix

General Operating Guidelines and Limitations

Table 1 Operating Guidelines

and Limitations

Operating System /
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 '{}' ';'
