PS4000 New Controller Different Firmware

If you swap a CM for a EQL you took the SD card from the old into the new one. The SD card is underneath.

I did not take the SD card out of the old one. That one stopped responding and we couldn't get it to work anymore. I thought if we took the SD card out, of the old one, it would still have the older firmware on it. We were hoping to keep the newer firmware. We don't have a way to download the latest version.

Thank you. I was hoping that just putting in the newer firmware card, that the one that is working on the older firmware would copy over the data, and we could just migrate to that one. Right now we are running on the older version. We cannot use the newer version one yet. 

From my brain...

1. Ensure that you boot the CM with your newer FW
2. login into the member and perform GrpName>update. Because you didnt uploaded a FW package i have in mind that the actual CM copy its FW over to the standby CM and restart the CM

You need the same version of the FW on each SD within the CM.

You can try to clone the SD with that newer FW to the old one.   I have something in mind that transfer of  FW is also possible from one CM to another. But EQL was long time ago .... you should search in the forum for some older thread.

The firmware on the one that is working is 7.0.1 and the newer one that we are trying to get working is 9.1.2

There where a lot of version between those two FWs.

Question: will the array boot with only one CM(try the newer one

Otherwise.. copy the FW manually from one SD to another. To be sure buy new SD cards.

Would you happen to know how to copy the firmware over? I don't have access to the firmware downloads page. 

You read the content from the SD with 9.x FW and copy it over to the other (or empty) one.

Thank you for your reply. We tried to boot to it, and it won't boot to the newer one. Had to resort back to the old one. 

Normaly EQL changed its active CM during every restart. What happens if you one boot one CM.... and insert the 2nd. one later.

What FW Version is on the CMs?

Hello, 

Do NOT do this!!!  Booting a different version of EQL firmware than what the RAIDset is NOT supported. That is not a valid way to upgrade the EQL firmware.  Only transferring a firmware kit and running the update process does that.  The "update" command that was suggested is ONLY used when the primary / active CM matches the EQL array FW on the RAID and the secondary/passive CM is at a different revision.  In that case the primary will overwrite the firmware on the passive and reboot the passive controller to bring them back into sync.  

 If you just try to copy the files over neither controller will boot.    If you want to do that you will have to completely RESET the array back to factory defaults, losing all your data. Then you could boot the newer firmware, configure the array.   Then install the CM with the lower firmware and use the update command to sync that higher FW with the passive.  Then restore all your data.

Yes, though you have to take an outage to do that. Also they wanted to UPGRADE to the new version but that can only be done via an update kit. 

 To make the newer FW match the existing version, you can run 'update' at the CLI, with NO firmware kit uploaded and it will downgrade the newer version to match the running version. 

 If you copied over the newer version to the older version SD card the array will no longer boot.

The most simple method is you can copy the total sd card content from your correct controller and then copy to the replacement controller SD-card. it workable.
