Novell Netware

Servers running Novell Netware require that the portdown value be reconfigured to allow enough time
for the storage systems to fail over.
To the end of the Fibre Channel driver load line of nwserver/startup.ncf add :
/LUNS /ALLPATHS /ALLPORTS /PORTDOWN=60

Oracle Solaris

Configure Oracle Solaris servers based on the version of Solaris running on the server.
NOTE: Changes to Oracle Solaris settings require a reboot before taking effect.

Red Hat Enterprise Linux

Timeout values determine the time a server waits before destroying a connection after losing
connectivity. With a single-path configuration that value should be set to 60 seconds to allow the WWN
of the failed port to transfer to a port on the other storage system. With a multipath configuration the
timeout value should be set to 5 seconds because the ports will fail over immediately. Configure the
timeout values as shown below based on the manufacturer of the HBA card and the path configuration.
