I wrote a short while ago about how our 9 month old son couldn’t get enough of the animated TV series Pocoyo. For those of you that are after some free Pocoyo episodes in English and other languages I have found the PocoyoUSA Channel on Youtube has plenty of episodes that can be viewed.

I wrote last week about having to manually fail a disk with faulty sectors in a MD3000i Disk Array before Dell came on site to swap the drive over.

clear allVirtualDisks unreadableSectors;
After this command the array appears to be fully functional and back as it was.

Inside this zip file was a file called unreadableSectors.txt. This file showed that the disk in slot 5, enclosure 0 was the source of these issues.
We had a hot spare available in slot 14, so before getting Dell to replace the faulty disk I decided to mark the disk as failed and get the Hot Spare to kick into action. Manually failing a disk on a Dell PowerVault MD3000i SAN Array is quite straight forward, but it isn’t something that is available in the MDSM gui. Below is the path to the utility and the command to fail disk 5.
