Refer to http://now.netapp.com/NOW/knowledge/docs/san/fcp_iscsi_config/QuickRef/SSICFMODE_1205.pdf

In a clustered system both nodes need to have their target ports set to the same cfmode. To summarise the different cfmodes, which ones to use and where:

cfmodeSupported systemsBenefits and limitations
partnerAll systems except FAS270, FAS60xx, and systems with 4-Gb adapters
  • Supports all host OS types.
  • Supports all switches.
single_imageAll systems
  • Supports all host OS types.
  • Supports all switches.
  • Makes all LUNs available on all target ports.
dual_fabricFAS270 only
  • Supports all host OS types.
  • Requires fewer switch ports.
  • Does not support all switches. Requires switches that support public loop.
standbyAll systems except FAS20xx, FAS31xx, and FAS200 series
  • Requires more switch ports.
  • Supports only Windows and Solaris hosts.
mixedAll systems except FAS270c and FAS60xx
  • Supports all host OS types.
  • Does not support all switches. Requires switches that support public loop.

thanks but when he was online all is ok, but when I stop FCP i have this message

When i try to do single_image, he say it's already in single image...

When you log into the other cluster node, what does a "show cfmode" return? Could you confirm that the other node is also in single_image mode?

It's ok !

i think is because i can't use 2 FC port on one node in my FAS2020
