Replacing FAS 2040R5 Controller

To Experts,

Following are the  errors I encountered upon replacing a  FAS 2040 Controller,

Upon autoboot  of the newly replaced controller I got the following error

   * Autoboot of primat_image failed. File not found (-18)


Then I performed the follow steps in-order to bring the controller up

1. First performing boot_diags on loader results into following error

LOADER-B> boot_diags

Could not load fat://boot0/X86/diag/kernel fat://boot0/X86_ELF/diag/diag.krn: Fi le not found

2. Secondly i tried performing a netboot using tftp server, it results into following error

LOADER-B> netboot tftp://192.168.1.1/734_netboot.e

Loading 192.168.1.1/734_netboot.e:Failed: Timeout occured Could not load tftp://192.168.1.1/734_netboot.e: Timeout occured

*** command status = -21

The reason i am doing this is to boot into maintenance mode and get the system id, and  reassign those disks again.

on the other hand,on test basis i ran this command

LOADER-B> boot_primary

Could not load fat://boot0/X86/freebsd/image1/kernel fat://boot0/X86_ELF/kernel/

primary.krn: File not found

*** command status = -18

All it reports is kernel error

Please advise a way forward

Re: Replacing FAS 2040R5 Controller

Did you move CF card from old controller to replacement one? Kernel is located on CF card, usually when you replace head you move it to ensure the same kernel version. In your case it appears that CF card on replacement head does not contain any kernel at all.

To do netboot you need to manually configure interface in loader (settings are not persistent, you have to do it every time after reboot). See https://kb.netapp.com/support/index?page=content&id=1012003&actp=search&viewlocale=en_US&searchid=1304058775436

Hi,


It truly makes sense, however the only removable parts in  the controller i encountered was NVRAM battery and SFP, please advise if there is anything other removable components.

Re: Replacing FAS 2040R5 Controller

CF is located on the bottom side under slide cover:

Re: Replacing FAS 2040R5 Controller

Hi Andrey,

Following your instructions opening  FAS 2040, the sliding cover [top] doesn't contain any CF Card on its underside, its a bare metal

please advise what shiould i do to bring this controller up.

Is there a possibility that CF Card is on board, and needs to be overwritten with new kernel.

Thanks

Re: Replacing FAS 2040R5 Controller

Have you actually read document that describes controller replacement?

“Remove the controller module, locate the boot device compartment on the underside of the controller module, and then

remove the boot device cover.

The boot device is to the right of center, near the I/O ports.”

It even has picture showing where it is located.

Hi,

Thanks for your support, actually i found the CF Card and replaced it from the old one

It read the the ONTAP 7.3.4 but i received the foolowing error upon boot up

Re: Replacing FAS 2040R5 Controller

Is NVMEM battery installed on replacement controller?

Link I gave you gives step by step instructions what to do to replace controller. Did you read and follow it?

Re: Replacing FAS 2040R5 Controller

Hi,

I followed the document step by step, however the controller boots, but the following error on the NVRAM Battery is being reported.
See the attached logs

The NVRAM Battery in the controller is
P/No: 271-00024, 18.5Wh, 7.4volt 2.5Ah Li-Ion Rechargable Battery

DOM: 2010-07-19

Re: Replacing FAS 2040R5 Controller

I think you really should open support case at this point. Assuming everything was connected properly there could be some firmware updates required, and NetApp support is in the best position to check and advice here.
