Start the Subnet Manager With the opensmd Daemon
If your InfiniBand fabric uses the Fat-Tree routing algorithm, you must provide a root node GUID file for the Subnet Manager. The /etc/opensm/guid.txt file is such a file. This procedure describes how to create the guid.txt file.
Type the following command on the management controller to retrieve the node GUID:
# ibstat |grep Node
For example:
# ibstat |grep Node
Node GUID: 0x0021283a8638b0f0
#Start a text editor on the management controller and record the GUID twice.
For example, you would see the following in the text editor:
0x0021283a8638b0f0 0x0021283a8638b0f0
Change the last two digits on the right from f0 to e0 for one of the GUIDs.
For example:
0x0021283a8638b0f0 0x0021283a8638b0e0
Save the text editor file on the management controller as the /etc/opensm/guid.txt file.
Set the permissions for the /etc/opensm/guid.txt file:
# chmod 0644 /etc/opensm/guid.txt #
