Is anyone running on OneFS 7.0.2.4 facing issue that Isilon is unable to detect new drive, the new drive is a replacement of failed drive.

Node: NL400

Thanks,

Damal

In the mean time, this issue can generally be resolved by powering the node down (not just rebooting, shut it down completely) and then turning it back on. You can leave the new drive inserted, the node should pick it up during startup.

Hi Damal,

What is the status of the drive?

By status I mean, [HEALTHY], [NEW], [REPLACE], etc.

You can check that out by :

     # isi_for_array -s isi devices | grep -v HEALTHY

Try using these commands for adding the drive:

     # isi devices -a add -d <node-number>:<bay-number>

     # isi devices -a format -d <node-number>:<bay-number>

If it still doesn't get added, try rebooting the node.

You can also refer to this: NL 400 Drive Replacement Guide

Cheers,

Anurag

The new drive installed, status shows up as empty. I am not sure if format is performed but i cant check on that.

We can drain the client connections and reboot the node, but reboot is not preferred. Actually the node rebooted by itself and not sure why it is

If status is empty even after adding the drive physically, try adding it the via command:

# isi devices -a add -d <node-number>:<bay-number>

I believe that step is part of procedure that CE is following to replace the disk.

But i will double check with him.

About the node reboot, support determined its a bug which will be fixed in 7.1.x.x, reboot caused by node panics - page fault in kernel module

The bug number is -119807


Is this what you asked for Peter.


Also i checked with few of my other colleagues about Isilon not detecting the replacement disk until node reboot, and they never came across this. They are on 7.0.2.4 as well. Is that a know issue ?

Thanks Damal

Just checked, no sight of 119807 in the 7.1.0.1 MR release notes.

As for the replaced disk not being recognized,

this has happened twice for us, but on 6.5 and IQ108NL.

In one case, just another drive was shipped that worked.

In the other case, we tried out three drives without luck.

Replaced the controller, still no drives worked in the particular slot.

Finally the whole chassis got replaced.

Cheers

Is the model of the new drive the same as the old drive?  EMC has been known in the past to change drive manufacturers and then you find out your drive is no longer on the supported list for the firmware you're running.

Double-check the node and drive firmware packages you have installed and update if necessary (which unfortunately requires node reboots).

Re: Isilon unable to detect new drive

When the node rebooted we actually had disk failures in two different nodes - one in each node and after drive replacements, both the nodes has to be rebooted to detect the new drives. So i am not sure if it a s/w or h/w fault but i noticed its happening in my environment only - OneFS 7.0.2.4.

The chassis replacement you mentioned about, were you on 7.0.2.4 ?
