Finally, I have resolved the issue by myself. I found this article which describes how to connect to the console interface with the IPMI tool. After connection, I saw both SPs are in the service mode and I got access to some service functions including reinitialization. So run reinitialization from the console and the array appeared online after that! Also, the full diag (svc_diag --state=spinfo) showed that SP B has broken BBU which probably was the reason why the array didn't go online after the first reinitialization.
Hi Everyone, I re-initialized our VNXe1600 in order to clear the old configuration and set it up from scratch. It is at the firmware v.3.1.9.9570228. But after re-initiatialization started and the SP's rebooted, it does not get IP by any of available methods.  The SPs are blinking blue and orange every 3 seconds as expected. I have tried to:  - discover it by VNXe Connection Utility (being on the same subnet, of course)- create a flash drive with config files and restart the device with the flash plugged in- put it on the network with a DHCP server none of these has helped to obtain an IP. Is there any way to set it up using a service connection or something like that? Or probably, reset it again without accessing to the WebGUI?
