Abank using the Oceanstor 9000 (v100R001) has officially started on-line operation and into the maintenance phase, maintenance engineer Zhang will be responsible for this. During the maintenance work, the need for periodic inspection of the health of the storage system, which of the following is the method of operation Zhang should. (Multiple choice)

A.

Zhang received maintenance tasks, immediately use the inspection tools configured for real-time inspection tasks, using the default business package, selectthe device to be checked, and check the project, immediately start the task of system-wide inspection, inspection results are normal

B.

Xiao Zhang plans to inspect the tournament site every Monday morning at 6:00 am, set up a time patrol strategy, patrolwith the start, end time and patrolCheck frequency, the configuration is complete and exit the inspection tool off, follow-up every Monday to see if there is any abnormal inspection report results

C.

Xiao Zhang When adding devices in the inspection tool, the configured device IP is the front-end IP address of one of the devices and the device is entered as requiredSSH login management user name and password

An N8000 file system can be used when offline command to query file system flag:

echo"8192B.p S" | fsdb -t vxfs / dev / vx / rdsk / sfsdg / sfsvol | grep flag

Where sfsvol is the name of the file system and may appear as flsgs 0 mod 0 Clean 3c or flags 4000 mod clean 3c if flags last bit is 0, then the file system is set.

A.

True

B.

False

On the command line of the N8500 (V200R001) clustered NAS system, you run the NFS> share add / vx / xs-cmfs 100.43.13.210 command.

One system that is used NFS sharing has IP address 100.43.13.11. If the client operating system is Suse Linux, which of the following access to the description of the file system is correct: (multiple choice)

A.

Not just the host with IP 100.43.13.210 can access this NFS share

B.

To query the client for all the NFS shares on the service IP, use the command: showmount -e 100.43.13.11

C.

Mount the NFS shared file system locally and execute: mount -t nfs 100.43.13.11:xs-cmfs / mnt

D.

Which of the following is not true about the Huawei OceanStor 18000 Smart Matrix architecture:

A.

scale-out: storage resources on-demand expansion, increase the engine to achieve performance, linear increase incapacity

B.

Full Exchange: The use of PCIE1.0 full switching interconnect, providing sufficient switching bandwidth to meet the stringent performance requirements

C.

Inherent Load Balancing: The controller is alive and well-balanced load sharing to improve storage resource utilization

D.

Full redundancy: Redundancy of all components, intelligent switchover of component failures to meet stringent business continuity requirements

Info Replication supports copying the data at the same time using the home directory, extended attributes, ACL (access control list), WORM, and CIFS. NFS configuration information is also copied to the slave. When a disaster occurs, the master and slave stations can quickly take over after the switchover.

A.

True

B.

False
