VNXE3100 Need to connect to console

Question

I have a VNXE3100. It is on loan and I have no support on it. I cannot connect to Unisphere. I have tried to change IP with a USB stick. When I press the password reset the status led blinks blue for a few second then goes out. I think I have to do a rescue on the storage processors. I would like to putty into the console with a serial cable. I believe it is the rj45 type plug with the spanner symbol. So is it like a Cisco cable, rj45 to standard db9? I just need information on the cable to connect it to a laptop serial port.

I don't think the service LAN port is used, but you can connect to the SP(s) using a serial micro db9 to db9 (rs232) null modem cable (which is supplied with the unit). This could connect to a serial adaptor on your laptop.

Serial parameters are 9600 baud, 8 data bits, no parity and 1 stop bit.

Any idea on the part number? I am off site and do not know if I need a micro db9 male or female.

I did find the correct cable, and was able to do a svc_reinit. Both controllers now have a solid blue led. I cannot seem to connect with the connection utility. Same vlan, same switch, no AV, and no firewall. I see in the utility I can use a usb and manually change the management IP. The usb should be bootable, but I cannot find any info on what bootable OS I should use. Any help would be appreciated.

Hi EMCNEW,

You don't need any OS to boot from USB. In fact it does not boot from that external USB.

Please use the KB article 14422 to troubleshoot the problem. If nothing works contact EMC support for help.
