Introduction

This article focuses on troubleshooting steps and methods for hardware problem of Avamar 4 and 4S node. It will help users timely to check the Avamar node. And also help you to understand the basic of Avamar hardware.

Detailed Information

Command reference table:

                           

Gen 4

Gen   4S

Check electric fan problem

omreport chassis fans

ipmitool sdr type fan

Check virtual disk problem

omreport storage vdisk

avsysreport vdisk

Check disk controller problem

omreport storage controller

avsysreport controller

Check system log

omreport system esmlog

ipmitool sel info

omreport system esmlog

Totally check hardware problem

omreport chassis

avsysreport chassis

Check power supply problem

omreport chassis pwrsupplies

avsysreport powersupplies

Temperature check

omreport chassis temps

avsysreport temperatureprobe

Memory check

omreport chassis memory

avsysreport memorymodules

Hardware log collection

dset_script

sysinfo -ni

Note:

If you are using an Avamar single node, you can connect directly to the Utility node through SSH, and then run the commands located in the table above.

If you are using an Avamar multi-node connect to the Utility node through SSH. Login to connect the utility node and storage nodes. Then use the command #mapall --noerror "<command>" to check the hardware problem.

For example:

#su – admin

#ssh-agent bash

#ssh-add ~/.ssh/dpnid

#mapall --noerror “<command>”

You can refer to the table above for the <commands>, except for "hardware log collection".

3.     Summary

Avamar is a very powerful backup software that shoulders the important data preservation function within an IT environment. Most of the commands listed in the table above be used for Avamar daily maintenance. It is strongly recommended to save this information for reference.

Re: How to quickly troubleshoot the hardware problem of Avamar Gen4 and Gen4S node

Hi Team,

Thank you for "Detailed models comparison table". However I would like to know the number of Disk Drives, Disk Drive Capacity and RAID Configuration.

As per my understanding

M2400 (7.8TB) –              12 x 2TB (RAID1)

M1200 (3.9TB) –              6 x 2TB (RAID1)

M600 (2TB)        –              6 x1TB (RAID1)

S2400 (7.8TB)   -              8 x 2TB (RAID 6)

Please correct me, If I am wrong.

Thanks & Regards,

Raghuram Bhat G

Please search "Location of the physical disk and which RAID group it belongs to on the Avamar node" in support.emc.com. The first search result is link to this KB article.

If you can't open the KB, that means your account permission is not high enough. We couldn't post content here directly since it is only available to partners.

Thanks for your understanding.

Re: How to quickly troubleshoot the hardware problem of Avamar Gen4 and Gen4S node

If you are only interested in Gen4S details then your initial question should be revised.

Here’s the details for the Gen4S RAID setup is which is identical to Gen4 and they are fully compatible with one another in terms of mixing them within a GRID.

I don’t believe there is any secret as to what the RAID setup is because this can be easily determined by anyone who has access to these nodes and it is only reasonable

a user would be interested in knowing this info as well. I suspect it is not present in customer facing documentation because Avamar H/W is sold as a an appliance therefore

no need for you to manipulate the H/W in any way.
