I am upgrading my virtual isilon cluster from 8.0.0.4 to 8.0.0.5 and it failed saying it cant find md5.

Any idea why I get this? Ofcourse i can do md5/sha256 on it with no issues and checksum is good

isilon-sim-3# md5 OneFS_v8.0.0.5_Install.tar.gz

MD5 (OneFS_v8.0.0.5_Install.tar.gz) = 7eb8c97d7f23e8602b7945e59f3571c3

isilon-sim-3# sha256 OneFS_v8.0.0.5_Install.tar.gz

SHA256 (OneFS_v8.0.0.5_Install.tar.gz) = 707f63afcd66502e80e0e0921254bfc3c1f5ef573ccfa42a93e880bd34321a34

isilon-sim-3#

Any idea why I get "ERROR Failed to install new image:No md5 exists, verifying md5 skiped"?

Thanks
