After review Brocade SAN switch errdump display warning "2021/05/18-11:15:04, [SWCH-1046], 67, FID 128, WARNING, Brocade_G610_A, Configured NPIV Login Limit of 0 exceeded on port index 1", check portcfgshow display all port "NPIV PP Limit 0".
We don't know why both new SAN switch setting with "NPIV PP Limit 0", after reset port to default "NPIV PP Limit 126", problem fixed.
Could you explain what you meant by "please review all devices error mesages first, do not trust the new device come with default setting. "?
We are missing review the SAN switch event and error messages when initial troubleshoot. Because it was new SAN switch and we assume the setting come with default.
Have you seen the issue return since you have made the corrective changes?
Issue did not return after change the SAN switch port config to default.
Were there any changes made prior to the port configuration change was reported/noticed?
Two SAN switch are fresh, but the port setting with NVIP PP limit is 0, this setting will not allow LIF login to SAN switc because the limit is 0. Check with Fabric OS port NPIV default setting should not 0.
Thank you for sharing your experience, it will be very helpful to the Community that we should check all settings as the default might not be the desired setting. I can confirm that the NPIV capability does need to be enabled and NPIV PP Limit configured to 126 per port on fabric switches. It is odd that the NPIV PP Limit was set to 0 as by default from Brocade it should be 126 and NPIV capability "disabled", so users only have to enable/disable the feature.
