EMC Storage Product Knowledge Sharing

1. Log into Connectrix Manager using the Username and password that was provided by the Customer. Note that the default username and password is Administrator and password. 2. You should now be in Product view. From Product view, double click on the switch Icon.3. You should now be in Hardware view. From Hardware view, move the mouse pointer over the Maintenance Icon and select the data collection option. In version 6.0 and above, you need to select the maintenance pull down menu and select data collection. 4. This will...

An LSAN is a Logical Storage Area Network that spans multiple Physical fabrics and allows specified devices from these autonomous fabrics to communicate with each other without merging the physical fabrics. In other word, A logical network that spans multiple physical fabrics. It allows specified devices from the autonomous fabric to communicate with each other using a FC router without merging the physical fabrics.- A LSAN zone is a traditional zone with a special naming convention.- Zone names must start...

Lets discuss about most important thing in SAN environment ZONING. Zoning is the only way to restrict access for storage to all the host. We will be discussing about Zoning in details.There are two type of Zoning basically : Hard Zoning and Soft Zoning. Lets first define what is Zoning??Zoning is nothing but map of host to device to device connectivity is overlaid on the storage networking fabric, reducing the risk of unauthorized access.Zoning supports the grouping of hosts, switches, and storage on the SAN, limiting access...

MDS Interoperability Mode Limitations When a VSAN is configured for the default interoperability mode, the MDS 9000 Family of switches is limited in the following areas when interoperating with non-MDS switches: • Interop mode only affects the specified VSAN. The MDS 9000 switch can still operate with full functionality in other non-interop mode VSANs. All switches that partake in the interoperable VSAN should have that VSAN set to interop mode, even if they do not have...

Vendor Worldwide Names WWN :Twenty-four of the sixty-four bit •World Wide Name• must be unique for every vendor. A partial listing of those vendors most familiar to EMC with regard to Symmetrix Fibre Channel connectivity.If decoding a HBA WWN, then issue an 8f, command to view the WWN in the FA login table. Bytes 1-3 of the World Wide Names contain the unique vender codes. Note that if there is a switch connected between the FA and the host bus adapter, then the name and fabric servers of the switch will login to the FA. These...

Brocade Switches:How to merge two switches with different active zone sets."Merging Two B-series Directors and/or Switches with Different Active Zoning ConfigurationsBefore Beginning The following procedure is disruptive to fabric traffic.:--It will require disabling the switch and the removal of the effective zoning configurations at one step. Removing this configuration will stop the data flow. Since this step in the procedure takes only a few moments to complete, data should resume as soon as the new configuration is activated.To...

There are different type of SAN like IP SAN, NAS over SAN etc... We will discuss about Fibre Channel SAN. It gives you more option in order to manage and minimize downtime means reducing company cost.In general if you think storage environments, physical interfaces to storage consisted of parallel SCSI channels supporting a small number of SCSI devices. With Fibre Channel, the technology provides a means to implement robust storage area...

You have two fabrics running off of two switches. You'd like to make them one fabric. How to do that? For the most part, it's simply connecting the two switches via e_ports. Before doing that, however, realize there's several factors that can prevent them from mergingg Incompatible operating parameters such as RA_TOV and ED_TOV Duplicate domain IDs. Incompatible zoning configurations No principal switch (priority set to 255 on all switches) No response from the switch (hello sent every 30 seconds) ...
