In the example above,
ib-admin
is the name of the user account,
privilege
is a mandatory
keyword, and
ib-rw
,
ip-ethernet-ro
, and
fc-rw
are access privileges.
NOTE: When you change a user’s privileges, all the old privileges are removed and replaced with the
new privilege(s). If the user had multiple privileges, include the other privileges on the command line
when you make the change. Privileges are order-dependent. Enter them in the same order as shown in
Table 6-2 on page 47.
Example
The following example gives a user read-write access to InfiniBand and Ethernet configuration
commands.
About Partitions
A partition defines a set of InfiniBand nodes that are permitted to communicate with one another.
Partitions provide:
• Security
• Allows a large cluster to be divided and isolated into small “sub-clusters.”
• Maps IB nodes to selected VLANs
How Partitions Work
A partition defines a set of InfiniBand nodes that are permitted to communicate with one another. Each
node may be part of multiple partitions so that a system administrator can define overlapping partitions
as the situation requires. Normal data packets carry a 16-bit P_Key, or partition key, that defines a
unique partition. The subnet manager configures each node's channel adapter with its set of P_Keys.
When a packet arrives at a node, the channel adapter checks that the packet's P_Key is valid based on
the subnet manager's configuration. Packets with invalid P_Keys are discarded. P_Key validation
prevents a server from communicating with another server outside of its partition.
