It would depend on the version of Navisphere CLI installed on the host the version running on the array - they should match. Also, some navicli commands will not longer work and have been replaced by naviseccli commands - in the CLI User Manual there is a section that explains the removal of navicli commands.  Navicli commands stopped being included with release 26. If you install R28 and higher and you do not already have an earlier version installed, you will not have access to "classic" navicli commands. Newer arrays may not response to older navicli commands. The release notes will provide more detailed information about this.  glen
Hi,  This is a linux 5.5 server . I have installed navicli rpm on it . naviseccli is working but navicli commands just hang. One of my application needs navicli to work. Any pointers as to why navicli is not working ?
