![]() ![]() ![]() There are tons of Unisphere software & agents.Home > Support > Software Downloads and Licensing > Downloads T-Z > Unisphere Server Software.Let’s download Unisphere Server Software from, you need a user account & password. But when we have multiple file, like A.NAR, B.NAR, C.NAR 1 st we have to merge A & B and then we have to merge the C file with the merged output of A & B. Regarding merging either thru Unisphere or naviseccli we can only merge two files.But if you want to do offline analysis, we need to install Unisphere Client & Unisphere Server Software (downloadable from EMC Powerlink) & use the same to open the NAR files for analysis.But we need to be connected to the SAN over wire. To retrieve, to merging & for analysis we can use Unisphere Archive Management feature directly from the storage box or naviseccli command line tool.So we would like to merge those files into a single file so it will be easy to analyze them. Well for a given day you may get 2 or more Archive files as per your archival interval setting. Next step for analysis is to download those Archive Log files.NAR/NAZ file title contains the date & time (in GMT) of last data point logged.And while you start with new time period it will start with new interval values. Before we change the archival time it is recommended to stop the logging, hence it will dump all data to NAR file and close that. ![]() Real Time interval is recommended to set lower or equal to archive interval because you will be watching real time graphs in Unisphere.So In case of VNX while doing performance troubleshooting it is recommended to set Archive Interval to 60secs & no more than 300sec. ![]() But higher intervals may miss key details about heavily loaded drives in a Pool. So default 120 value may not work here, we may like to increase to 300sec. Having said that if we have bigger SAN environment it make take more time to pull the data from SP.
