Steps to follow to replace a Failed Drive in PS6100

Hi,

I am new to these Devices, in my environment we have 2 Dell EquilLogic devices and we got Failed drives on both devices. These are out of support i believe 😞

Slot Type Model Size RPM Status Errors SMART Health
---- -------- ---------------- ----------- ----- --------- ------ ------------

1 SAS(HDD) Unavailable 0MB 10000 failed 0 unavailable

2 SAS(HDD) Unavailable 0MB 10000 failed 0 unavailable

7 SAS(HDD) Unavailable 0MB 10000 failed 0 unavailable

Is it straight forward to replace these? Like Order new Drives and pull the failed once and replaced with new?

If not do i need to follow any other steps from CLI or GUI before and after the replacement?

 

One more Query:

I can also see it has some failed components but it's now showing what exactly failed?? Is there a way to find out what failed here?

Health Status Details 

Critical conditions::
Critical hardware component failure.

Warning conditions::
More spare drives are expected.

any help would be a great help and much appreciated.

Thanks in advance.

Re: Steps to follow to replace a Failed Drive in PS6100

Hello, 

 Yes,.  Basically replace them and the rebuild will start.  There are no commands to issue. 

 However, you can't use OEM or NON-EQL drives in the 6100.  Even other "Dell" drives, like from a server or other SAN will work.  They are branded specifically for the EQL storage arrays.   So you will need a vendor that has drives for EQL arrays.  I would replace them one at a time.  Is this data backed up? 

 You might want to check the service data for that array, you might still be able to get it back under contract.  If you go to support.dell.com and enter in the service tag, you can see he ship date.  You can get up to 7 years from that date. 

 Regards, 

Don

@DON can you also let me know how to check what other failed components in the device from the CLI?

Re: Steps to follow to replace a Failed Drive in PS6100

Hello, 

 The "failed component" is likely to be the failed drives.  It's a general flag to indicate something has failed.  Then the last time "more spares expected" is the reason.  It's looking for spare drives to start a rebuild

Regards,

Don

Re: Steps to follow to replace a Failed Drive in PS6100

Hi Don,

Thank you..

is there a command in CLI to view the disk rebuild status and time? not sure but i can't open the GUI session due to some errors.

also in one of the system there are 2 failed drives to i have to do it one by one right? is this means wait till a drive completely rebuilt and do it the next one?

Regards,

Santhosh Kumar

Hello, 

At the CLI: 

member select MEMNBERNAME show    (Look for RAID percentage)

Re: Drives.  Since they have both failed but you are still online you can replace them both. It will put a greater load on the member while the rebuilds are running.  

What RAID level is that member using?  

 Regards,

Don

Hello, 

 Since the drives are 10K RPM and 500GB the rebuild time should not be very long.

Re: Steps to follow to replace a Failed Drive in PS6100

Hello, 

 Or the rebuilds had already finished and you just replaced the two consumed spares. 

member select ITFC-EQL-U44-N1 show disks 

 I suspect you will find two drives marked as SPARE now. 

 Regards,

Don

Re: Steps to follow to replace a Failed Drive in PS6100

Hi Don,

These drives failed a few days ago, may be a week to 10 days.

Yes, as you said i can see these replaced drives as Spares.
