down failure) before the last chunk gets initialized,

primary array could end up sending incomplete message

to secondary array and hence cause the IO hung. This is

resolved and it makes sure that skip re-read operation for

WRITE_SAME_ZERO request is performed only if all the

chunks are initialized for the entire IO.

amount of virtual memory. To resolve this, execute

showvv, showvlun, showvvcpg, statvv and

statvlun commands in a child process. When that

process exits, the memory is available although there is

a very small increase in latency.

Remote copy header validation is improved to avoid issues

when two remote copy arrays are configured with the

same IP address on RCIP networks.

Remote copy header version checking is

improved.

to perform the check and it does not give a false positive

is resolved by disabling this command.
