EqualLogic PSM4110 Firmware Downgrade from v7
Hello all
I have a new PSM4110 that came with firmware v7.0.5 on it.
I need to join to a group with a PS5000, PS300's and another PSM4110 with firmware v6.0.7
Firmware downgrades are disallowed in the group by default - I don't need the data on the old unit so it's OK to reset.
Is there a procedure for downgrading? Again, the new unit has no data.
THanks in advance
/Philip

I opened a case with Dell. They were able to work with me to force downgrade the firmware (includes resetting the unit back to defaults).

Problem solved:
I worked with Dell support to force-downgrade the firmware which also resets the configuration (read: Lose any Stored Data!)
Once it was on the earlier firmware, I joined it to the group.
Don -- The switches are Power Connect 8000 series (10GBit)

Hi Don,
We're only grouping them together long enough to get the data off the PS300's so they can be retired.
THe older units are in their own storage pool so the data isn't spread across interface types.

What about the PS5000? That too is end-of-life? You can add the 7.0.x array to the 6.0.x group.
What 10GbE switches are you using? Using 10GbE ports on GbE switches doesn't work and isnt supported. They aren't designed for 10GbE SANs and typically result in poor performance and stability.

Hello Phillip,
Are you planning on retiring the old units? Dell doesn't support mixing EOL and non EOL hardware for production use. Mixing 10GbE with GbE is tricky. The PSM4110 doesn't sync down to GbE.

OK. Glad they were able to work with you on that.
re: 8000. Suggest you make sure it has latest firmware.
