how to collect the S.M.A.R.T Information of Disks ?

Publication Date:  2014-09-17 Views:  66 Downloads:  0
Issue Description
- customer in two weeks has two failed disks , and  there is no problem  found after analyzing logs.
- we need to collect  S.M.A.R.T Information of Disks  to check its status .
Alarm Information
alarm :

Handling Process
- On the CLI, run the showupgradepkginfo -t 1 command to view the system software version.
- Collect the S.M.A.R.T information of disks based on software versions.

1- Collecting the S.M.A.R.T information of disks for V100R002C00SPCg00 and later versions:
-------------------------------------------------------------------------------------------------------------------------------------
note :-  
 - On the CLI, run the developer command and enter the password debug@storage ,then Enter minisystem.

1. Collecting the S.M.A.R.T information of a single disk

------------------------------------------------------------------------------
 - Run the disktool -f a /dev/sdxx command to collect the S.M.A.R.T information of a single disk. Copy the command output to the file.
- To view sdxx, run the showdiskinfo enclosureid command (enclosureid referring to the enclosure ID) in minisystem mode. Find the name of the disk.
For example, the name of the disk in slot 0 enclosure 0 is sdg.

2. Collecting the S.M.A.R.T information of all disks :
-------------------------------------------------------------------------

- In minisystem mode, run the disktool -f A, command to collect the S.M.A.R.T information of all disks. Copy the command output to the file.
Note: You are advised to collect the S.M.A.R.T information of all disks when the service amount is small
Root Cause
- we need to collect  S.M.A.R.T Information of Disks  to check it status .
Suggestions
- S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; often written as SMART) is a monitoring system for computer hard disk drives (HDDs) and solid-state drives (SSDs) to detect and report on various indicators of reliability, in the hope of anticipating failures.
- When a failure is anticipated by S.M.A.R.T., the user may choose to replace the drive to avoid unexpected outage and data loss. The manufacturer may be able to use the S.M.A.R.T. data to discover where faults lie and prevent them from recurring in future drive designs.
- Hard disk failures fall into one of two basic classes:
    1- Predictable failures result from slow processes such as mechanical wear and gradual degradation of storage surfaces. Monitoring can determine when such failures are becoming more likely.
    2- Unpredictable failures happen suddenly and without warning. They range from electronic components becoming defective to a sudden mechanical failure (perhaps due to improper handling).
