In order to verify the consistency of the slave LUN data with the source data and to protect slave LUN data, which of the following descriptions is incorrect:

• Create a virtual snapshot of the slave LUN and activate it, then map the snapshot LUN to the host for authentication.
• After the snapshot LUN is mapped to the host, the host can read and write the snapshot LUN.
• After the verification is completed, stop the upper-layer service application, release the LUN mapping, and finally delete the snapshot.
• Stop the snapshot before the host can write snapshot LUN.

Users use vsphere 5.5 to build business virtualization. In the course of the operation it was found that a host was using too many SCSI reservations, leading to vmfs performance degradation. What method can be used to eliminate the root cause of SCSI reservation conflicts? (Multiple choice.)

• Reduce the number of snapshots.
• Reduce the number of virtual machines per LUN.
• Increase the number of LUNs and limit the number of hosts accessing the same LUN.
• Change the type of virtual disk created.

• Thin LUN and thick LUN can be configured with the same capacity.
• Both thin LUN and thick LUN can make initial capacity allocations.

Huawei Oceanstor 9000 provides a single file system to the outside through the unified file system namespace management. Which of the following description is correct? (Multiple choice.)

• The namespace is automatically created when HUAWEI OceanStor 9000 is started with the same name as the system namespace.
• Namespaces as the root directory of the entire system can not be shared and visited, only if ask the subdirectories below it can be shared and visited.
• A unified namespace provide users with a unified storage resource pool to achieve the centralized management of storage space and distribution.
• Each file share directory is a subdirectory of the namespace.

In preparation for disaster recovery design, which of the following is correct?

• Use the same type of disk as the master
• Raid should be set the same as the master
• The capacity of Lun and primary LUN is the same
• Use the same number of disks as the master

In the Huawei OceanStor system, the size of the file system block is a measure of the size of the accessed file system block. The size of the block is designed according to the size of the data block. Different size of the file system block selects the corresponding file system block, according to the size of the data block. If the business scenario is the media, for large file archiving or stagger I / O backup scenarios, it is recommended to choose the default 64KB disk block size.

• True
• False

• pfile parameter file

In a manual recovery process, which of the following operations is not required? (Multiple choice.)

• Stop the current production business, delete the host mapping.
• Adding the remote device to the original production side array.
• With the disaster recovery array as the master LUN and the original production array as the slave LUN, create the remote replication relationship between the DR and the production end and wait for the initial synchronization to be completed.
• Make an incremental synchronization.
• Delete the original production array consistency group.

Erasure code redundancy technology is a data file is divided into ODC (M logo) equal length data blocks, generated by encoding RDC. Any of the RDC fragments can be restored out of the original file, which can tolerate up to ODC node failure, to achieve the purpose of data protection.

• True
• False
