This read-only Counter holds the high-order 32 bits of the count of data octets received by the local iSCSI node on this session, combined with cpqiScsiSsnLCRxDataOctets (actual count equals this times 2^32 plus the low counter) for systems lacking Counter64 support. An admin uses this pairing to track cumulative inbound data volume on sessions carrying more traffic than a plain 32-bit counter could hold. For example, when auditing bandwidth usage on a very active session, an admin's script reads both received-octet counters together to avoid undercounting after a 32-bit wraparound.
