Once OMSA is installed it is accessed and used the same as if it was on a windows box.  You can monitor, manage, and setup  alerts. support.dell.com/.../OMSA_ug.pdf There are several  videos listed here, support.ap.dell.com/.../ss_omsa Which can help familiarize with the software.  You can also use the OMSA CLI to perform most tasks. support.dell.com/.../index.htm I hope this information helps to clarify what the software can do, including monitoring RAID array status and any failures. Thanks.
Hello, I'm planning to install OMSA package from Dell repository ([URL]#OpenManage_Server_Administrator) to monitor my RAID array. The server is on line so I would like to ask if it's necessary to reboot it to install any of the packages from this repository. Is there any potential issue that I may experience during this process? Kind Regards
