Pulling logs on MD3060e via serial for SDS solutions

When using Software Defined Storage (SDS) with the MD3060e dense JBOD, there is no support for shmcli in operating systems like Nexenta.
This article will help to pull the required logs from the system by connecting to the Enclosure Management Modules (EMM).

Note: You have multiple options with pulling logs, e.g. telnet or serial.

Telnet or serial into the EMM

Default IP addresses

The default IP addresses for the EMMs are

• EMM 0 (Top) - 192.168.128.101
• EMM 1 (Bottom) - 192.168.128.102

"Already in session" warning

If the telnet session says "already in session" please run the following command:

• echo "q" | telnet IP address

Note: Depending on the IP address the command will be different.
