Hello,
how about you take the SSD from 0:8:0 and put it to 3:23:0
The other disks you have to replace i guess.
Run showpd -i <PD ID Number> to get the model of the disk.
It is a good practice to check :
showpd -space <PD ID Number>
before replacing. It should show all the size in failed.
For the disk in cage4 there should be some more investigation.
Eventually you can manually run servicemag and then replace it once it is finished.

Hi Yavor,

I replaced the disk on 0:8 location with same 200GB SSD but it gave error resuming serviemag. error is "New disk 146 is smaller than replaced disk 8". Is there a way to force servicemag to use the current disk given its same type? May be the new one is off by few bytes :?:

So....

you have 3 failed drives...
450GB 10k FC drives in 0:8:0 and 4:13:0
200GB 150k SSD in 3:23:0

Why are you still trying to push the SSD into 0:8:0? That slot is waiting for a 450GB 10k FC drive... The SSD needs to go into 3:23:0...

Thanks Mammagut. I think i got confused with the disk and inserted incorrect one in the slot...I placed the SSD on 3:23:0 and looks like it went fine but the old PD ID is still showing up and new PD is normal. I will post another thread.
