Hello, 

 Can you access the chassis individually?   Can you ping all interfaces on every chassis?  

 That is a very large group to not have a support contract.   Do you have a contract for these ? 

 If so, I suggest you open a support case. 

 Regards,

Don

Hello, 

 Also, are all the volumes available?  (online) 

 if so then you could have a GUI problem not a problem with the chassis's themselves. 

 If you connect to the CLI and do GrpName>show members    Does that show all the members? 

 Regards,

Don

The problem is solved there were some firmware updates applied while I was gone and some of the controllers were not acting right so rebooted the controller and all is good now thanks for the responses.

Hello, 

 So glad you worked it out.  Thank you for updating us as well. 

 Regards, 

Don
