disk replacement issue

Hi All,

 

lately we had a 146GB disk part of RAID1 volume on MSA1000 with a predictive failure state. So, we proceeded to replace this disk with one with same capacity. However, the rebuild failed. Does it have anything to do if disks have different rotation speeds? Note that the defective's RPM is 15K and the new one is 10K.

OS is redhat linux 5.0

 

Thanks in advance

Re: disk replacement issue

Hi,

 

Replacing the disk with a different speed is not an issue. 10K disks are out of production for some time now.

 

There could be some other issue which is causing the rebuild issue, checking the logs can give you more information

Hari

Re: disk replacement issue

Hello,

 

actually there is no more LED signals on the replaced disk however, all disks on the MSA are flashing red; what does this mean exactly?

 

Thanks in advance

Re: disk replacement issue

Most likely someone has ACU open and the controller selected.

Did you try to get the status from ACU?

Hope this helps!

Torsten.
