Hi Friends
I do not understand the situation arose
All i/o channels active stated.
san-switch device firmware upgrades.
Was a sudden san-switch reboot .
the san-swtich of the i/o channels disable.
the normal state of other channels
For a while, but the service was not 30 second.
I wonder why this happened.
I think, 30 seconds as the service stops, the dmp reforming.
Tell me, what was the other possibility.
thanks
