A physical disk detected a warning value

Jump to solution

Hi-

We have a failing drive with following info gleaned from MegaCLI...

C:\>megacli64 -PDInfo -PhysDrv [32:13] -a0 -NoLog | grep -E "(Slot Number:|Count:|Firmware state:|S.M.A.R.T)"
Slot Number: 13
Media Error Count: 94
Other Error Count: 0
Predictive Failure Count: 6
Firmware state: Online, Spun Up
Drive has flagged a S.M.A.R.T alert : Yes

Can we force it "Offline" and "Replace Member" - instead, of waiting until it fails completely?

Thanks for any input.

Hello.

What server and controller do you have? A drive in a predictive fail state shall fail any ways. Go a head and replace this drive, you don't to wait for it to fail. If the drive is a hot swap, you do not have to first offline it before replacing.

Hi-

Thanks - I would like to swap asap.

T620 w/ PERC H710 Adapter (SSA/SATA).

Flashing orange then green right away.

Have the extra drive w/ carrier/caddy ready to go...

Also - we'd like to replace when there is less activity on server - rebuild will affect performance.

This is a data disk or has SQL server DB's in production on it - our primary Application utilizes it all day.

Waiting for after hours - preferably a weekend - not sure of rebuild time - 2TB(SAS 15K) VD/Array...

There is no defined rebuild time as it is dependent on the size of the disk, I/O operations, etc. Good call!

Robert-

Appreciate your fast response times.

Last question related to Machines w/ Hot Swap drives and Dell(LSI?) PERC/RAID Controllers...

Do we need to research or lookup the type of Dell machine(Gen 11,12,13,etc?) + Controller(H700/710, etc.) to be sure it can hot swap before failing or if in a predictive failure/Smart alert state?

Thanks again.

Yes, you can always research on such information. Generally, hard drives connected to back-planes are hot swap drives as opposed to cabled dives
