This OID is a 64-bit fault-aggregation bitmask summarizing outstanding faults raised against the launched, deployed instance of an iSCSI vNIC as it actually runs on a server, as opposed to the vNIC's policy-level definition (IScsiLCP), without an admin having to walk each individual fault object. This is operationally useful because a non-zero value tells an admin at a glance that this particular IScsiLCP instance has an active problem — such as a failed pin group or missing pool — worth investigating further. For example, a monitoring script polling many iSCSI vNICs at once could flag only the ones where this fltAggr value on the IScsiLCP object is non-zero, instead of walking the full fault table for every vNIC.
