It is not an easy to remember the commands since most of the UNIX administrators are working on multiple Operating systems and different OS flavors. Exadata and ZFS appliance are adding additional responsibility to Unix administrator and need to remember those appliance commands as well. This article will provide the reference to all Exadata storage cell commands with examples for some complex command options.
All the below mentioned commands will work only on cellcli prompt.
