Hi thethakuri,   yes, it's possible to hot-swap the hard drive. It is not shown in the section of the physical disc, so it is not just offline but entirely down. Pull it off the system and replace it with a new/replacement hard drive and check that the rebuild starts. Here's a guide if needed: PowerEdge HDD: How to physically replace an HDD (Hot-Swap procedure)   If not, assign the new disk as a global hot-spare, the PERC will do the rest.  Here's another guide: Dell PowerEdge: How to Assign a Hard Drive in Global Hot Spare?   Generally, the backplane doesn't fail - I'm pretty sure this is related to the defective hard drive. You will see if the error disappears after replacing the drive.   Let me know if you need any further help.   Best regards,Stefan
I noticed that one of the virtual disk had degraded: [IMAGE] From logs, the HDD in slot 7 failed, which caused the above-mentioned Virtual Disk degradation. [IMAGE]   Also, Backplane Connector is now showing critical. [IMAGE] But in the physical disk list, Disk in the slot 7 is missing. [IMAGE]   My questions are: How do I replace the failed drive in slot 7? Do I just hot swap or should I do it from the boot menu ? Please explain. What about Backplane Connector is showing critical? Is that related to slot 7 HDD failure ?
