Hi PKPhu,  The Mellanox IB switches for Isilon are all considered to be an un-managed switch. If set up properly, the cluster should automatically notify you if one of the IB interfaces goes down. You can also check their status at any time in the webui or from the command line using the following command:  #isi_for_array -s "ifconfig ib0 && ifconfig ib1"  Mellanox may have more documentation, but it is highly recommended that no changes be made to the configuration of the switch. If there is disruption to the IB communication, you will not be able to access the data on the cluster.
Hi all, I have 2 IB Switchs IS5200 8 ports for Isilon cluster. How to monitor their status? Please help me, thanks!
