The following list describes the limitations of UNIX-based clients:
UNIX-based clients cannot use user IDs or group IDs 999999 and 1000000
for real users or groups; these are reserved IDs that are used internally
by SAN File System.
Tip: To avoid any conflicts with your current
use of IDs, the reserved user IDs can be configured at installation time.
You cannot use multibyte enablement for items referenced in a file-placement
policy (such as storage pools, filesets, parts of file names).
The mkfs command is not supported in UNIX®.
All AIX-based clients must reside in the same authentication domain for
correct mapping of user and group IDs.
This table lists the values for the maximum size of a file
that SAN File System supports for each AIX® platform:
