EMC 數據清空

1.數據清空

這裡會清空file system的所有東西包括tapes

sysadmin@FSEMC01# filesys destroy

The "filesys destroy" command irrevocably destroys all data in
all the MTrees, including all virtual tapes, archive units and replication contexts.
The 'filesys destroy' operation will take about 2-3 minutes.
File access is disabled during this process.
    Are you sure? (yes|no|?) [no]: yes

ok, proceeding.

Please enter sysadmin password to confirm 'filesys destroy':
......
The filesystem is now disabled.
Destroying the filesystem.

The filesystem has been destroyed.

2.重建

sysadmin@FSEMC01# fi st  --檢查文件系統是否存在
The filesystem doesn't exist.

sysadmin@FSEMC01# vtl tape show all  --顯示tape狀態
Processing tapes....

VTL info cache is unavailable.
Please use the "vtl status" command to verify that vtl is enabled and the VTL process is running

sysadmin@FSEMC01# filesys create --文件系統創建
A filesystem of approximate size 15.83 TiB will be created.
    Do you want to continue? (yes|no) [yes]: yes

ok, continuing.

This will take 5 - 10 minutes.

Provisioning storage...
########################################### [100%]

Initializing filesystem...
########################################### [100%]

snapshot schedules deleted

You now have a freshly initialized filesystem.
 Enable the filesystem using 'filesys enable'.

sysadmin@FSEMC01# filesys enable  --enable文件系統
Please wait.............
The filesystem is now enabled.
sysadmin@FSEMC01# vtl status --檢查vtl的狀態
VTL admin_state: enabled, process_state: starting, licensed
sysadmin@FSEMC01# vtl tape show all   --檢查tape
Processing tapes....
No tapes.

然後我們去創建tape在圖形界面

點擊create tapes  填入Number of Tapes, Starting barcode,Tape capacity

這樣destroy 和重建就完成了。剩下去NBU備份那裡重新掃描這些磁帶。

regards!
