What switches do you have in your M1000? This is where you need to disable DCB (like Don said). I assume your PS6500 is plugged into a racked switch and not the switches in the M1000. Your rack switches may not support DCB or just has it disabled and therefor the PS6500 says it's disabled. However, if your M1000e has 8024-k switches, MXL switches or IO aggregators, you may need to explicitly disable DCB on those switches.

ok thanks.

We have separate Storage Pools for PS6500 and PS-M4110 all uses same group manager IP

on PS6500 I can see DCB status off on all 4 1 GB NICS.

on PS-M4100 I see two NICS. 10G interface which shows DCB on and 1GB interface which shows DCB OFF.

I have asked network guys to check network configs

Is there a command I can to explicit disable on 10GB interface ?

Thank you. We discovered its enabled on switch connecting to PS-M4110 and we can disable it.

Currently we are in version 6.0.7 PS6500 and 6.0.6 for PS-M4110 and planing to upgrade to 7.0.5. Is DCB configuation required to upgrade to Equalogic firmware 7.0.5 ?

thank you for the reply. We dont use VMFS datastores for ESXi from Equalogics yet. Everything connects through ISCSI initiator on windows VM

yes working on upgrading to 7.0.5

Disabling DCB on switch took care of the warning. However 10G interface of array shows its being ON. No need to disable on interface or how we can disable on array interface ?

yes I restarted the controller and 10 GB port now shows DCB status as off

what is effect of enabling DCB back on EqualLogic? I meant should it be in a maintenance window and imply downtime ?
