Drive Connectivity Failover

Thefull‐heightLTO‐4FibreChanneldrivesareequippedwithtwoFibre

Channelports. ThetwoFibreChannelportscannot beus ed simultaneously

toprovideredundantdatapathsbetweenthehostsandthedrive.

However,theycanbeusedtoprovidefailovercapabilityintheeventthat

communicationtothe

portcurrentlyinuseisinterrupted.Thisfailovercan

beaccomplishedinoneofthefollowingways:

 Manuallydisconnectthefiberopticcablefromthefailedportand

connectittotheotherport.Youmayneedtoreconfigureyourhost

softwaretorecognizethealternateport.

 ConnecteachportonthedrivetoaseparateFibreChannelHBAinthe

host.Youcanalsouseadual‐portFibreChannelHBA.Configureone

HBA(orHBAport)astheprimaryconnectionandtheotherHBA(or
