Once the ip info is set on SPA you must reboot the Navisphere Management Server before setting the info on SPB.
A Sun host with two HBAs is direct connected to a CX600. Which two EMC Software packages should be used on the Sun host? (Choose two)
Answer B, the EMC Navisphere Host Agent, is server-based software that communicates with Navisphere client applications, such as the Navisphere Command Line Interface (CLI) and Manager, to manage pre-FC4700 storage systems. The SP Agent (Array Agent), which resides on the storage processors (SPs) in CX-series and FC4700-series storage systems, communicates with Navisphere client applications to manage CX-series and FC4700-series storage systems.Host Agent automatically registers host and HBAs and also provides drive-
mapping information for the UI and CLI. The Host Agent has no direct user interface. Therefore, it must be configured with the remote agent configuration feature of Navisphere Manager or CLI or by editing the Host Agent configuration file. Answer D, PowerPath, is EMC's latest host-based multi-path failover software, providing load balancing and failover capabilities on hosts with more than one HBA and more than one path to a CLARiiON SP. (Note: without failover software on the host, only a single path to each SP is supported.) Answer A, the ATF-Application Transparent Failover software, was used on earlier CLARiiON arrays and is no longer supported. For that reason, this answer is incorrect. Answer C, the Navisphere Manager 6.X is a Web-based product that communicates with software called the Storage Management Server software that runs in SPs or on Windows servers. Because it doesn't work with Sun hosts, this answer is also incorrect.
A user has installed a new LP9002 card in his Windows host. The user wants to hard code the HBA to run only in 2 GB mode. How can this be accomplished?
Edit the emulex.conf file to set the "link control speed" to 2 GB.
In the Emulex Configuration Utility, under settings>link control; set it to 2 GB mode.
Select the SP under the network tab and set it to 2 GB mode in Navisphere Manager.
Set the negotiate speed toggle to 2 GB mode on the HBA.
The exlcfg ( Emulex Configuration Utility ) supports hard coding of the Emulex 9002 HBA. Answer A is incorrect because there is no emulex.conf file created on the Windows host. Answer C is incorrect, because the SP network tab does not allow the option of setting speeds for HBAs. It does allow the settings of SP IP addresses, subnet masks, and gateway settings. Answer D is incorrect because this option is likewise not available.
Company has just completed the attachment of a Windows 2000 server to a SAN- attached array. Which file shows where the privileged user list is defined?
The agent.config file is a host resident file that contains the list of privileged users who will be allowed to communicate to the SP, as in firstname.lastname@example.org Host Agent is still required for the registration of the host bus adapters with the SPs to which they are connected and for integrating host-side information such as device and volume names. Answers A, C, and D are bogus file names to which no actual host files correspond.
A six-drive RAID-1/0 RAID Group needs to be expanded. What is the maximum number
of drives that can be added to this RAID Group?
A RAID 1/0 group can contain anywhere from 4 to 16 disks added in pairs. This means the only valid numbers of disks are 4, 6, 8, 10, 12, 14, and 16. Adding ten drives to the existing six brings the total up to 16, the maximum number of drives allowed in a RAID 1/0 group. That's why only answer D is correct, and all the others are wrong.
A user wishes to bind 32 RAID 5 LUNs on a CLARiiON Fibre Channel array. Which step
must be performed before a user can bind the RAID 5 LUNs?
Create a RAID 5 Volume Set.
Create a RAID Group that contains at least three disk drives.
Create 32 RAID Groups.
Format the Fibre Channel disks using Navisphere CLI.
Format the Fibre Channel disks using Navisphere Manager.
A RAID 5 Group usually consists of five disks (but can have three to sixteen). A RAID 5 Group uses disk striping. With a RAID 5 group, you can create up to 128 RAID 5 LUNs to apportion disk space to different users, servers, and applications. Answer A is incorrect because you cannot create Volume Sets with Navisphere. Answer C is incorrect because you need to create only a single RAID group with 3 or more drives. Answers D and E are
incorrect because you can use neither Navisphere CLI nor Navisphere Manager to format a disk.
Which of the following is a benefit of striped metaLUNs over concatenated metaLUNs?
Full capacity is available immediately upon creation.
Increased data throughput.
Less strict LUN selection criteria.
More resistant to data corruption.
Striping data across more physical spindles increases random, small block I/O performance. Answer B is incorrect because the full capacity of a striped metaLUN is not available until the striping is completed. Answer D is incorrect because striped metaLUNs are indeed restricted by RAID type and capacity. Answer D is incorrect because the striped metaLUN inherits the host facing characteristics of the base LUN and is thus neither more nor less resistant to data corruption than that base LUN itself.
In Navisphere Manager, the CX400 shows SPA as unmanaged and SPB as managed. What
might be the cause of the problem?
SPA is not in the correct RAID Group.
SPA is not in the correct Storage Group.
SPA is not properly cabled to the Ethernet LAN.
SPA is not properly cabled to the Fibre Channel SA.
For Navisphere Manager to communicate with the array an SP must have a valid IP address, gateway, and subnet mask. Navisphere Manager is a browser-based application and relies on Ethernet connectivity to manage storage arrays. Answer A is incorrect because membership is a RAID Group has no effect on the management of the SP. Answer B is incorrect because membership is a RAID Group has no effect on the management of the SP, either. Answer D is incorrect because SAN membership occurs using WWNs and should not affect Ethernet connectivity.
Company wishes to use SnapView to perform nightly backups of a database with minimal impact on database performance. Which two programs can be used to script automated backups? Select two.
The Navisphere Admsnap utility is an executable program that runs interactively via a script to manage clones. The admsnap utility resides on hosts connected to the storage system through the SnapView driver. The Navisphere CLI complements or may be used instead of Navisphere Manager. It provides a command line interface for storage-system management, including storage provisioning, status and configuration information retrieval, and control. Use the CLI to automate management functions through shell scripts and batch files. CLI commands for many functions are server-based and are provided with the Host Agent. There is no program known as Navisphere Backup, making answer B incorrect. Navisphere Manager does not support backup among its functions, which include: discovery of CLARiiON storage systems, status and configuration information displays, event management, and storage configuration and allocation.
