At the beginning of the VTL6900 system input, you need to prepare the physical device. As shown in the figure, the VTL6900 is the cut-off point of a physical device node on the VTL console. On the physical equipment to prepare this step, which description is correct? (multiple choice)

A. The equipment in the picture has completed the equipment preparation step

B. The corresponding LUN in the figure is a LUN created on the service hard disk of the engine

C. Change the equipment status is normal

D. The process of preparing a physical device is the process of virtualizing a LUN mapped from an array, similar to a quick format

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

The N8000 file system is based on dynamic hierarchical storag. Through the multi-volume file system, you can achieve the same file system text pieces stored in different levels of storage media, such as hot data and ordinary data stored in the SSD disk and SATA disk.

A. True

B. False
