after reboot vnx SP , host initiator not log in partly

is this happening for all hosts ? and if yes  are these showing 'not logged in ' with the same SP port ?

…..may I know if you have noticed any port failures in the SP’s…?

Yes showing not log in is it upgrade needed? The newest oe is 5.011

Before The reboot the host were all log in , but after reboot,all host show not log in for the same sp port.the host were all log in to switch.

Just see the status of A0 and B4 ports.

Check the port status physically and also from switch to confirm the ports are working fine. Seems to be some issue with storage ports only.

Was the reboot a planned one ?

Was there any changes at the hardware/software level recently ?

Yes,all host. PortA0and B4.

If the ports are logged in to switch, just see from the host side the ports are connected or not (from powerpath etc...). You may try also, restarting management server for both the SPs.

If still the issue persists, I will suggest you raise a Service Request with EMC support.

and you have verified these systems are logged-in to the switch ?

Yes  i plan to reboot the sp. I have not do any thing before reboot.

The port 's status is ok . I check it  already .

Perhaps no port failed.because before I reboot sp all port workwell

thank you for your answser , i have restart the sp manager , but the problem still exists . 

i read some other forum

i was troubleshouting ,and will tell you the newest info.

the reboot was planed . and before rebooting i have done nothing change , i check the sp fc port and it work fun , sppeed auto . i am updating the block oe of the vnx .

and see if any thing could change .

Hi, in first check SAN switch (i think u have few ports with errror) can disabled/enabled portd and than refresh initiators on your vnx.

see also right click on the storage group, properties and enter engineering mode (Ctrl +Shift+F12 password messner). Hosts tab, advanced, all paths should have a check mark next to them.
