The MIB's DESCRIPTION for cucsLsIdentityInfoWriteMode is only the auto-generated stub 'Cisco UCS ls:IdentityInfo:writeMode managed object property', but the 'writeMode' property name together with its CucsLsIdentityInfoWriteMode type tell us this column, on the record of how a service profile's UUID identity was assigned (from a pool, or hard set), holds the writeMode as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The writeMode controls how this service profile's UUID gets written to the physical server's hardware (e.g. only on first association versus every time), using the CucsLsIdentityInfoWriteMode enumeration. A profile expected to reuse the same UUID across server swaps would use a write mode that reapplies the identity every association rather than only once.
