Example of OpenSM partitions.conf file:
cat /etc/opensm/partitions.conf
Default=0x7fff, ipoib, defmember=full : ALL, ALL_SWITCHES=full,SELF=full;
Test=0x1, ipoib, defmember=full : ALL, ALL_SWITCHES=full,SELF=full;
The “ALL” will configure all the HCA guids in the fabric, including the vGUIDs for both the default and non-default PKEYs.
The customer needs to isolate the traffic per host. Meaning all HCA GUIDs should not members of the non-default partitions.
Therefore, they added the actual needed HCA GUIDs to the non-default partition and included the 8 skyway GUIDs.
Example:
Test=0x1, ipoib, defmember=full : ALL_SWITCHES=full,SELF=full; 0x…..1, 0x……2, skyway guid1, skyway guid2, …., skyway guid8;
What is needed is all Skyway GUIDs including the vGUIDs.
Current way to get them:
-
Configure the partitions.conf file on the SM node as below.
cat /etc/opensm/partitions.conf Default=0x7fff, ipoib, defmember=full : ALL, ALL_SWITCHES=full,SELF=full;
-
Run ibdiagnet on one of the IB host.
-
Run the below to get all skyway GUIDs from the ibdiagnet2.vports_pkey file.
# cat /var/tmp/ibdiagnet2/ibdiagnet2.vports_pkey | grep <skyway host name> | awk -F "guid=" '{print $2}' | paste -s -d "," | sed -e 's/,/, /g' > filenameLab example:
# cat /var/tmp/ibdiagnet2/ibdiagnet2.vports_pkey | grep skyway | awk -F "guid=" '{print $2}' | paste -s -d "," | sed -e 's/,/, /g' > /tmp/skyway_guids.txt
-
Edit this file to add the needed partitions.conf configuration and replace it with the old one.
