Methods used to expand the storage capacity of a VM

6

You can expand a VM's storage capacity as follows:
1. If the storage resources of the FusionCloud desktop system are insufficient, you can add new storage devices and migrate some VM disks to them. For details, refer to the product documentation. Alternatively, you can delete VMs that are not in use to release their storage space.
2. If a single VM's storage space is insufficient, you can add a new hard disk to it.

Hard disk capacity expansion for the USG6000 series
The USG6650/6660/6670/6680 supports dual hard disks. Do as follows to install a hard disk on the USG, which has been running for some time with a single hard disk: 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, remove the filler panel from the hard disk slot, and install a new hard disk unit. a. Remove the filler panel from the hard disk slot. HDD1 is used as an example. b. 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. c. Press the tray handler inwardly to restore the tray. d. 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. In this example, the command shall be reset raid primary-disk 0. Several hours later, run the display disk information command. If Filesystem Status is Mounted and DiskRaidMode is ACTIVE, both hard disks work properly. Note: After the RAID is created, the data in the active disk will be synchronized to the backup disk and the original data on the backup disk will be overwritten. Select the disk-id of the active disk before creating RAID.
