54) What Is Lun Masking?

Ans: LUN (Logical Unit Number) Masking is an authorization process that makes a LUN available to some hosts and unavailable to other hosts. LUN Masking is implemented primarily at the HBA (Host Bus Adapter) level. LUN Masking implemented at this level is vulnerable to any attack that compromises the HBA. Some storage controllers also support LUN Masking.

55) Why Do We Need Lun Masking?

Ans:

Do you want to excel in computer field? Are you familiar with computer embedded systems? Wanted fetching and growth in your job? Then move on to wisdom jobs online portal and explore your career. EMC is an electromagnetic compatibility, the use of components in electronic system that do not electrically interfere with each other. EMC storage refers to various storage products, systems which are essential for virtualized and cloud computing environment. Candidates who are willing to join in EMC jobs have a wide scope in EMC design jobs, Embedded Developer jobs, embedded engineer jobs, embedded software developer jobs, EMC compliance testing jobs, EMC symmetric jobs and so on. So, grab the opportunity by looking at the EMC interview questions and answers framed below.

LUN (Logical Unit Number) Masking is an authorization manner that makes a LUN to be had to a few hosts and unavailable to different hosts.LUN Masking is applied broadly speaking on the HBA (Host Bus Adapter) stage. LUN Masking carried out at this level is prone to any attack that compromises the HBA. Some storage controllers additionally aid LUN Masking.

Use the Persistent Binding for Tape Devices. Persistent binding is a host-centric enforced manner of directing an working device to assign certain SCSI goal IDs and LUNs. Persistent Name Binding support is for target devices. Persistent binding is supplied for customers to companion a certain tool World Wide Port Name (WWPN) to a exact SCSI target ID. For instance, in which a particular host will usually assign SCSI ID 3 to the primary router it finds, and LUNs 0, 1, and a couple of to the 3-tape drives connected to the router. Practical examples:For Emulex HBA on a Solaris host for putting in place chronic binding:# lputil MAIN MENUList Adapters Adapter Information Firmware Maintenance Reset Adapter Persistent Bindings Using choice 5 will perform a manual continual binding and the document is: /kernel/drv/lpfc.Conf file.Lpfc.Conf file seems like:fcp-bind-WWNN=”50060XY484411 c6c11:lpfc0t1″, “50060XY4411 c6c12:lpfc1t2”;sd.Conf record looks as if: call=”sd” parent=”lpfc” target=1 lun=zero; name=”sd” figure=”lpfc” goal=2 lun=zero;Reconfigure:# touch /reconfigure # shutdown -y -g0 -i6

The device covering instructions can help you:Assign and mask get admission to privileges of hosts and adaptersConnected in a Fibre Channel topology to garage arrays and devices.Specify the host bus adapters (HBAs) via which a bunch can get admission to garage arrays devices.Display or list tool overlaying gadgets and their relationships: Typical gadgets are hosts, HBAs, storage arrays gadgets, and Fibre Channel Adapter (FA) ports.Modify properties, along with names and get entry to privileges related to tool protecting gadgets (as an example, trade the Name of a bunch).

Q. Which protocol is used by open systems hosts to access storage in Fiber Channel SANs?

Hard zoning is zoning that is applied in hardware. Soft zoning is zoning that is applied in software. Hard zoning bodily blocks access to a area from any device out of doors of the region. Soft zoning makes use of filtering applied in fibre channel switches to prevent ports from being seen from out of doors in their assigned zones. The security vulnerability in smooth zoning is that the ports are still reachable if the consumer in another area correctly guesses the fibre channel address.
