they are configured down. If an e0M interface is serving management
traffic, it should be partnered with another e0M interface.
For more information about e0M configuration, see the Data ONTAP 8.0
7-Mode System Administration Guide.
4. If your systems include e0P interfaces for controlling SAS storage
expansion units, ensure that they are connected only to a private ACP
network or that they are configured down. e0P interfaces should not be
partnered.
For more information about ACP configuration, see the Data ONTAP 8.0
7-Mode Storage Management Guide.
Additional SAN upgrade requirement
If your storage system is in a SAN environment, you must ensure that your
SAN configuration is fully supported. All SAN components—including the
target Data ONTAP software version, host OS and patches, required Host
Utilities software, and adapter drivers and firmware—should be listed in the
IBM N series interoperability matrix, which is accessed and navigated as
described in “Websites” on page 149.
Additional requirement for AT-FCX storage expansion unit firmware
updates
The topic "Service availability during storage expansion unit firmware
updates" currently lists two requirements for updating AT-FCX storage
expansion unit firmware non-disruptively: minimum firmware version and
Multipath Storage configuration. There is an additional requirement that Data
ONTAP 7.3.2 or later be running.
The first row of the table should read as follows:
Module
Storage expansion unit
model
System downtime
required?
AT-FCX EXN1000 With Multipath Storage,
firmware version 37, and
Data ONTAP 7.3.2 or later:
No Without Multipath
Storage: Yes
After the table, the AT-FCX information should also be updated to state that
you cannot perform a Data ONTAP nondisruptive upgrade (NDU) under the
following circumstances:
v AT-FCX storage expansion units are attached to your system and one or
more of the following is true:
– You have not verified that the latest AT-FCX firmware version is
running.
