Bad SD Card on PS6100 - need to upgrade firmware on different SD card
I have a PS 6100 with two Type 11 controllers. One of the controllers went to not being present. I obtained a new controller and installed that with the SD card from the previous controller. The new controller also showed as not present. I out the old controller back in, using the SD card from the new controller and it does show as present but it has firmware v7.1.14 while the active controller has v9.1.9. I cannot update the firmware to v9.1.9, getting an error that the controllers have different firmware. Is there any way to get the v7.1.14 controller up to the same firmware as the active controller? The initial issue appears to be a problem with it's SD card, not a bad controller per se.

Solved!
Thanks Don, I was able to move the unit to a maintenance pool, vacating its data to two other units, then power it down, pull the SD Card from the "good" controller and copied those files to a desktop folder. I reinstalled the good controller and pulled the downlevel controller out. I removed its SD card and overwrote the files with the files copied from the "good" controller. I powered up the SAN with just the good controller installed and after that came up (forcing the "good" controller to be the active one I installed the second controller hot. After some minutes this controller came up and now has the same firmware and all is happy.

Hello,
Something you can try. Those versions are pretty far apart so this may not work.
Make sure the CM with the 9.1.9 FW is the ACTIVE controller.
SSH (or serial port) to that member. With NO firmware kit uploaded to that member. At the GrpName> prompt type:
GrpName>update
This will attempt to copy the FW from the active (9.1.9) to the passive v71.14. over the internal bus between the CMs. If it works it will restart the passive controller and it will come back online at 9.1.9.
Alternatively, shutdown the array. Pull the SD card from the primary and clone it over the SD card. Then reinstal the SD cards and boot up the CM that was working as the primary. Then insert the passive CM once the array is booted.
Regards,
Don

Hello,
You are very welcome and thank you for the update. Just curious, did you try the "update" procedure? I wanted to see if it worked with revisions that far apart.
Regards,
Don

I did not try the update procedure because there are two other group members. Since I had the SD Card with the downlevel firmware already on it - just overwriting the files with those of the uplevel card did the trick nicely and the PS6100 gets to play in the default pool again.

Hello,
Thanks for replying. A couple of things. You can always move a member into a new pool at any time. The move will appear immediate and in the background the data will be rebalanced between the members. As a follow up, with mulitple members in the same pool with the data now stripped between them if one member should fail, all the volumes they have in common will go offline also.
The (default) pool is a leftover artifact from many years ago, it has no functional significance. In fact you can set any pool to be (default)
Regards,
Don
