Mounting hard disks for the USG6000 series

34

After hard disk installation for the first time on the USG6000, the hard disk will be automatically mounted upon device power-on and startup. Run the display disk information command to check whether Filesystem Status is Mounted. If yes, the hard disk works properly.
The USG6000 also provides the disk online command that enables the hard disk to go online and to mount services. For example, after hard disk replacement when the device is powered on, you need to run the disk online command for the hard disk to start work. After running the disk online command, you can also run the display disk information command to view the hard disk mounting result. If Filesystem Status is Mounted, the hard disk is successfully mounted.

Installing hard disks for the USG6000 series
For the USG6000 (1 U device), perform as follows to install the hard disk combination SM-HDD-SAS300G-B for the first time: 1. Loosen screws on the filler panel and remove the filler panel. 2. Hold the two side surfaces of a hard disk unit, push the hard disk combination into the slot along the guide rails until it is well seated into the slot, and fasten screws on the two sides of the hard disk unit. 3. After that, run the display disk information command in the user view. If Filesystem Status is Mounted in the command output, the hard disk is successfully installed. For the USG6000 (3 U device), perform as follows to install the hard disk unit SM-HDD-SAS300G-A for the first time: 1. Remove the filler panel from a hard disk slot. 2. Hold the handlers of the tray and push the tray along the guide rails inside the hard disk slot till the tray panel aligns with the panel of the device. 3. Press the tray handler inwardly to restore the tray. 4. If there are two hard disks, repeat steps 1 to 3 to install the other hard disk. 5. After the installation completes, check as follows: -If a single hard disk exists, run the display disk information command in the user view. If Filesystem Status is Mounted in the command output, the hard disk is successfully installed. -If two hard disks exist, run the display disk information command in the user view to check whether the Filesystem Status value is Un-Mounted and the DiskRaidMode value is INACTIVE. Then, in the system view, run the reset raid primary-disk disk-id command to create a RAID group using disk-id as the primary disk for data synchronization. The synchronization process will take several hours. During data synchronization, other services can be used, but the hard disks do not record real-time logs for the services. After data synchronization completes, the hard disks automatically start to work. You can run the display disk information command in the user view on the next day to check whether Filesystem Status is Mounted. If no, contact Huawei technical support personnel. When a hard disk is faulty, replace it. For details, see content relevant to replacing hard disks on the USG6000 series in the product documentation.

Replacing hard disks for the USG6000 series
If a hard disk is faulty (for example, a hard disk failure log is generated on the USG), you can replace the hard disk unit. The hard disk unit can be replaced no matter when the device is powered on or off. If the device is powered off, skip step 1 and do not run the disk offline command. The following procedure guides you through hard disk unit replacement while the device is powered on: Note: In case of dual hard disks, replace the faulty disk with a new one. Do not change slots of the hard disks. Otherwise, the device may fail to recognize the hard disks. After replacing the hard disk, run the disk online command in the system view. Otherwise, the hard disk does not work. For dual hard disks, data is automatically synchronized between the hard disks after the disk online command is run. The synchronization takes several hours. During the synchronization, do not insert or remove the hard disks. Otherwise, data loss may occur. 1. Ensure that all configurations are saved. 2. Run the disk offline command in the system view. Wait for about 30 seconds until the system indicates that the hard disk stops working and then remove the hard disk unit to be replaced. a. Press the button on the right of the hard disk tray to eject the handler. b. Use the handler to pull the hard disk unit out of the slot. c. Put the replaced hard disk unit into an ESD bag. 3. Install the new hard disk unit. The hard disk unit installation methods are the same for 1 U and 3 U devices. For details, see content relevant to installing hard disks for the USG6000 series in the product documentation. 4. Run the disk online command and then the display disk information command in the system view. If Filesystem Status is Mounted, the hard disk works properly. Note: For dual hard disks, Filesystem Status becomes Mounted several hours after the disk online command is run. During this period, you can use other services, but the hard disks do not record real-time logs for these services. After data synchronization completes, the hard disks automatically start to work. You can run the display disk information command in the user view on the next day to check whether Filesystem Status is Mounted. If no, contact Huawei technical support personnel.

Formatting hard disks for the USG6000 series
The USG6000 hard disk supports formatting. However, formatting a hard disk may cause disk data to be lost. Exercise caution when you perform this operation. To format a hard disk, run the reset disk command in the diagnose view. system-view [sysname] diagnose [sysname-diagnose] reset disk

Full disk scanning for hard disks of the USG6000 series
Disks may be bumped during delivery, which may cause disk failures. Before usage, you can perform full disk scanning to repair the disks. Full disk scanning takes 2 to 3 hours. Note: Hard disk self-check interrupts hard disk services. Exercise caution when you perform full disk scanning. 1. Install the hard disk to the device. 2. In the system view, run the disk offline command to enable the hard disk to go offline. 3. In the diagnose view, run the disk self-test enable command to perform full disk scanning. 4. In the diagnose view, run the display disk self-test command to view the result of disk self-check. Progress: displays the progress. For example, in 2/46, 46 indicates that the operation may take 46 minutes, and 2 indicates that 2 minutes have elapsed. The actual time taken shall no longer than 46 minutes. Otherwise, the disk is faulty. ErrorType: Selftest complete without error: indicates that the hard disk is not faulty. Send command failed!: indicates that you shall run the self-check command again. Other: indicates that the hard disk is faulty, and you need to replace it or contact professionals for analysis. DiskSN: indicates the SN of the current hard disk. The self-check result corresponds to the SN.
