[FrenkArd]

Nobody has moved the cables...another ideas?

[Torsten. · Accepted solution]

check all the I/O B modules, maybe one is dead

[FrenkArd]

Hello Torsten,
maybe you have reason, because the two led of the module are off (i attached the picture).
There is some way to add a disk in a group also with the loop error? Because maybe there is not fast to get and replace the broken module.

Thanks

This could mean this module is bad or the next module in the chain.

compare to the status shown in command view.

disk replacements should be possible.

Hello Torsten,
i tried to change the disk but i receive the error in attached, why?

From command view i can see only the status that i attached in the previous post (connection status: link lost).

[Torsten.]

What was the action? Remoce disk? Group disk?

How many disk yhassis do you have?

[FrenkArd]

I'm trying to add an ungrouped disk in a disk group (the disk was in fault and i changed it).

In total i have 3 enclosure with 36 disks.

At the end i changed the IO module and now it works.

Thanks
