3PAR message "NL tier has disks exceeding low water mark of recommended IOPS"

Hello,

my customer has 3PAR 8200 installed last january. Today he call me to ask if I know what means the message

"NL tier has disks exceeding low water mark of recommended IOPS".

But I never seen this before today.

Does anyone can explain to me the means of the message and if is necessary some corrective action ?

Thanks in advance

Davide

Re: 3PAR message "NL tier has disks exceeding low water mark of recommended IOPS"

The Low Watermark IOPS for NL Disk is 75, high is set to 120.

This means the NL Disk can safly handle up to 75 IOPS and he have Disks with higher than 75 IOPS.

I see this most Times during the Backup Time.

Look at the Report in https://www.storefrontremote.com to see the Issuse and how to handle.
