MSA per disk health statistics

[RoelofStrydom]

Good day all, 

Apologies is this has been asked already. 

Is there a CLI command to export per disk statistic to let you know the "life" remaining on each disk in the MSA?

Thanks in advance.

The specific command or method to export per disk health statistics from an MSA (Modular Storage Array) may vary depending on the specific model and firmware version of your MSA. However, in general, HP MSA storage systems provide a command-line interface (CLI) or management software that allows you to retrieve disk health information. Here are a few general steps you can follow:

* Connect to the CLI or management interface of your MSA. This can typically be done through SSH or a serial console connection.

* Log in to the CLI using the appropriate credentials.

* Once logged in, navigate to the section that provides disk-related information. This may be a submenu or a specific command.

* Look for a command or option that displays the health and status information for each disk. Commonly used commands include "show disks," "show physical disks," or "show disk status."

* Execute the command, and you should see a list of disks with their associated health and status information. This information may include details such as disk temperature, SMART data, estimated remaining life, and any reported errors or warnings.

Please note that the exact command and output format can vary depending on the specific MSA model and firmware version. Please refer the user guide for your particular MSA model to find the appropriate command or method to retrieve per disk health statistics. Additionally, make sure you have the necessary privileges and permissions to access this information through the CLI or management interface.

Hope this give some insights. Let me know

Thanks Vinky_99, 

it gave me some good info, but not sure what Lifetime Read and Written means, this is shown as 0B for both values. Example of a few lines.

For spinning media you could look at the Power-on hours (8760hrs/year) and validate that so the drives you have are 42000 hrs so closing in on 5yrs. 
For SSDs run the CLI command>  show disks detail  {disk ID}

Look for 'SSD Life Remaining'  and 'Power On Hours'

For some supported disks in the MSA the lifetime writes/reads will not display.  The SSD life remaining is really the only true deterministic detail which will give accurate info on drive life.  Spinning media is less deterministic about remaining life.
