症状



All Hosts were not logged in from some ports
Example: B2- slot 2 and A0-slot2

原因

From some ports, connection was not re-established between switch and storage after upgrade.

解决方案

- Reset the port from switch side before going on with the next steps from Unisphere.

If initiators are not logged in, try the following from Unisphere:
- Reset the speed from Unisphere --> settings --> network --> right click on port with issue set speed from auto to 8G--> click apply--> ok
Then right click again on port with issue set speed back to auto --> click apply --> ok
- Re-scan all hosts, wait couple minutes and refresh all initiators.
- Hosts from ports that had speed reset are now logged in.

其他信息

- If there are no changes occurred from VNX side (i.e. no upgrades, no reboot, no cabling changes, etc.), check the switch side.

- If switch is supported by EMC, gather switch logs and engage switch team for further investigation.
