Dell PowerEdge 6850 Degraded HDD

delldell-poweredgeraid

Good Morning,

We have a dell power edge 6850 with a degraded drive in the RAID array.

I have never had to recover such an issue, so any help or advice would be welcome.

Basically it hasn't affected the server at an operating system level, but has slowed down performance, I have a replacement drive in hand but as this is our main database server I want to proceed with extreme caution.

My options as I see them are –

  1. Can I just hot swap the degraded drive with the new one and the data will automatically re-sync and we are all back to normal presumably this is dependant on the current raid configuration?

  2. reading various comments on-line I may need to re-configure the RAID array and re-build the broken drive? This screams disaster to me with the main worry being that I wipe any other data.

Option 1 would of course make my day.

Thanks in advance

You had never a degraded raid? Strange. The first thing you should try is to pull out the "broken" drive and put it back in again. Sometimes the drives just get thrown out but have no defect.

If this works the drive will blink green and start to rebuild at once. If it fails the drive will blink orange again - then the drive is really faulty.

If the drive is faulty you can replace it with a new one. If you did not fiddle with the RAID-controllers default settings, it will rebuild automatically. (PERC4i?)
