Question about ESXi 6.5 iSER driver with PFC port configuraion.

1

Hi!

I saw a Mellanox iSER driver for ESXi 6.5 released.

But this driver seem to be need Global Pause configuration on each ports that show on driver’s manual.

Is there any solution with PFC configuration on switch’s ports?

Best Regard,

P.S

Why iser storage adapter disappeared after every ESXi 6.5 host reboot?

P.S 02

This Global Pause based iSER initiator can’t connect SCST Ethernet iSER Target.

How can I resolve this problem?

Tested iSER Target

  1. LIO

  2. SCST

  3. StarWind vSAN

here are some fine articles that Mellanox published on how to configure PFC on Mellanox switches

For switchX

For Spectrum switch

As for the other issues you raised (iser storage adapter disappeared after every ESXi 6.5 host reboot + iSER initiator failing to connect SCST ) - this I believe requires a whole session of troubleshooting logs & dumps so suggesting that you approach support@mellanox.com mailto:support@mellanox.com , describe the problems in details and get advised by relevant Mellanox support engineers
