NetApp predictive disk failure
Posted on 2014-08-30
I have a 2246 SAS shelf and I'm tired of waiting for disks with predictive failures to fail before hot swapping so my question is how would I properly fail a good disk that is only predicting to fail? Here are some of the commands but I'm not sure which ones to use.
Disk Fail command forces a file system disk to fail and will be selected for Rapid RAID Recovery and copied to a spare. You must use the disk swap command afterwords when using SCSI disks. (we use SAS, does this not apply?)
Disk Replace command can be used to replace a file system disk with a more appropriate spare disk.
Followed by a disk swap?
It's not clear in the man disk pages on which to use in a predictive failure situation.
Thanks in advance
