Hi Rainer,  Adding here the response from Engineering:    - Losing 1 System Disk: no impact   The system should function fine but will affect performance since all the system RGs will be degraded   - Losing 2 System Disks (Any difference between losing 0 and 2 or 1 and 2?)   Yes if you lose 0 and 2 or 1 and 3 they are Mirror boot drives and it might take one of the SPs down i.e 0 and 2 for SPA and 1 and 3 for SPB. If you lose 0 and 1 or 2 and 3 or some combination other than both the boot drives of the SP, then cache might be disabled since the vault LUN will go offline.   - Losing 3 System Disks (Let's say 0, 1, and 2)   Array will panic    - Losing all 4 Disks (Let's imagine that someone comes in and takes them out). Is the array still recoverable if it has not been powered down?   Array panics with 3 faults    Thank you, Luis
Hi,  A customer has a VNX2 series and lost a system drive and questions about losing more systems drives came up. On VNX2, system drives don't have spares so, what happens in the following scenarios:  - Losing 1 System Disk: no impact - Losing 2 System Disks (Any difference between losing 0 and 2 or 1 and 2?)- Losing 3 System Disks (Let's say 0, 1, and 2) - Losing all 4 Disks (Let's imagine that someone comes in and takes them out). Is the array still recoverable if it has not been powered down?  Thanks!
