Internal Boot Drive replacement

sjones5,

Just in case its the NL400 chassis would you happen to have that replacement document too?  I totally understand, but this customer I am working for has experienced numerous boot disk failures on this cluster and is accustom to just doing this themselves.  So I am trying to make sure I have the information I need to continue this process.  Let me know about the document for the NL400.

Many thanks!

Hi chjatwork,

While I am sure the customer is completely capable, if they have a support contract, they are not to replace the boot drives on their own. If they do, they risk voiding that support contract. The standard disk drives are customer replaceable, but the boot drives are not. Anything that requires opening up the node, must be done by a certified engineer.

Here is the NL400 documentation as well:

sjones5,

They are fully aware of this that's why they have me on staff as a resident.  I am able to replace these disk.  I just would like to have the documentation on hand for reference and best practice.  I am glad that my account level can access the links so all is well.

Many thanks again for following up with me!

We had local EMC Support replace our boot drive but the support engineer generated replacement documentation from SolVE desktop application.

I was wondering if you have this documentation for the x400?  I am also looking for the part number for the boot drives if you have that as well.

Thanks

The service has elapsed on this cluster

I found this part number in my notes: Drive Part Number: 403-0114-01

isi_for_array -s isi_radish -a /dev/ad* | grep -E "Percent Life" | grep -v Used | awk '{print $1 $2 $3 $4 sprintf( "%d","0x"$9 )}'

Will display wear life for each drive in every node in the cluster, which is nice

Hi jarec007,

The documentation for the X400 is here: https://support.emc.com/docu44413

As far as finding a replacement part, you have a couple options. You can do a Time and Materials quote for the part replacement through Isilon to have them replace it. They will need the serial number of the node in question.

If you are looking to purchase a boot drive from a third party, I don't know that the Isilon part number would be valid outside of Isilon's dispatch system.You could however find a compatible model number. If you know what firmware version you are on, check the release notes. Otherwise you should be able to see what model you currently have with this command:

#isi_radish -q /dev/ad[0,1,2,3,4,7]

As a side note, if you are running anything below 8.0, you can use [2,3,4,7]. In 8.0 OneFS started streamlining the boot drive names to ad0 and ad1. The command above should work on your X400 though. It doesn't change anything, It just provides an informational output.

Just know that if you do go the third party route, Isilon won't assume any liability for it.

isi_for_array -s isi_radish -a /dev/ad* | grep -E "Percent Life" | grep -v Used | awk '{print $1 $2 $3 $4 sprintf( "%d","0x"$9 )}'

Hello trying to run this command on a cluster running Isilon OneFS v7.1.1.4. the output of isi_radish -a /dev/ad* does not contain "Percent Life"  I do see this line...

Percent of Total Wear: 01/64 vs 00 (raw 000000000000) [flags 0003]

how can I tell what percentage of life is left on a cluster that is running OneFS v7.1.1.4?

You'll probably want to confirm with support but I believe (raw 000000000000) is the hexidecimal value for the status of life remaining, and in your case it is zero.

Is it a SANDISK boot drive? If yes, Then make an SR and ask the wear life. I have not seen anywhere where Isilon can track the wear life info on SANDISK ssd bot drives.

Thank you Phil

Hi

Is this part number 053-0027-01 used for the boot drive for Isilon NL400 nodes?

Yes it is, all Gen 4 nodes will use that part number for boot drives
