Whether hosts can a ccess a volume larger than 2 TB depends on the operating systems of the hosts.

Hosts running the following operating systems can access LUSE volumes larger than 2 TB:

• AIX 5.2 TL08 or later

• AIX 5.3 TL04 or later

• Windows Server 2003 SP1 or later

• Red Hat Enterprise Linux AS 4 Update 1 or later

Cautions

• O ther op erating systems do not suppor t LUs larger than 2 TB. If other operating systems are used

by hosts, make su re that the LUs are not larger than 2 TB.

• For information about the maximum LU capacity supp orted by your operating system, contact the

vendor of your op erating system.
