download. By default, downloading a SAS image does not remove the installed
SA images. If this option is specified, the installed SA images are removed. This
option is only valid with the -a sas option. This operand is no longer supported as
of Fabric OS v7.0.0.
Bypasses the checking of Coordinated HotCode Load (HCL). On single CP
systems in InterOp fabrics, the HCL protocol is used to ensure data traffic is
notdisrupted during firmware upgrades. This option allows firmwareDownload to
continue even if HCL is not supported in the fabric or the protocol fails. Using this
option may cause traffic disruption for some switches in the fabric.This operand is
no longer supported as of Fabric OS v7.0.0.
