Oracle ILOM uses a firmware version numbering scheme that helps you to identify the firmware version you are running on your server or chassis monitoring module (CMM). This numbering scheme includes a five-field string, for example, a.b.c.d.e, where:
a - Represents the major version of Oracle ILOM.
b - Represents a minor version of Oracle ILOM.
c - Represents the update version of Oracle ILOM.
d - Represents a micro version of Oracle ILOM. Micro versions are managed per platform or group of platforms. See your platform product notes for details.
e - Represents a nano version of Oracle ILOM. Nano versions are incremental iterations of a micro version.
For example, Oracle ILOM 4.1.2.1 would designate:
Oracle ILOM 4 as the major version
Oracle ILOM 4.1 as a minor version
Oracle ILOM 4.1.2 as the first update version
Oracle ILOM 4.1.2.1 as a micro version of 4.1.2
Oracle ILOM 4.1.2.1.a as a nano version of 4.1.2.1
