Add optional values to ipmi.bmcport to support more fine-grained
configuration for Dell servers, and mirror the `ipmitool delloem`
capabilities:
lan set <Mode>
sets the NIC Selection Mode :
dedicated, shared with lom<idx>
lan set <Shared Failover Mode>
sets the shared Failover Mode :
shared with failover lom<idx>
shared with failover all loms,
shared with failover none.
This patch introduces the possibility to provide 3 (space-separated)
values for ipmi.bmcport:
1st value: 0 = shared / 1 = dedicated
2nd value shared LOM (1-4) (0 or no value means first available LOM)
3rd value: failover LOM (1-4) (0 means no failover, no value means all LOMs)
To ensure maximum compatibility with the default 0/1 shared/dedicated
scheme, the 2nd and 3rd values are optional, and will retain the
previous behavior when not specified.
Examples:
ipmi.bmcport value BMC interface configuration
0 Shared with first available interface, failover with
all LOMs (catch-all mode)
0 1 Shared with LOM1, failover all LOMs
0 1 2 Shared with LOM1, failover LOM2
0 2 0 Shared with LOM2, no failover
1 Dedicated
* bmcsetup: revert previous meaning of bmcport for Dell servers, to
conform with other server types: 0=shared, 1=dedicated
* bmcsetup: remove dependency on `ipmitool delloem` and use raw cmds instead
ipmitool delloem may not work on all Dell server generations,
functionnality depends on ipmitool versions (see
https://github.com/ipmitool/ipmitool/issues/18).
So removing thatdependency and using raw IPMI commands seems more robust.
Don't check $LOCKEDUSERS at all, instead fall back to userslot 2 as a last resort if the user doesn't already exist, and the automatic slot detection doesn't find an unlocked slot. This is essentially what was happening in the older version of the script before #6380 as $LOCKEDUSERS was only ever referenced here.
Also move setting the username before setting privileges and access levels, as those steps fail if done before username is set for the slot.
Instead of relying on hard coded offsets, query each slot's status with ```ipmitool channel getaccess``` and use the first slot that is unlocked.
This fixes an issue on certain Cray x86 nodes that have arbitrary locked IPMI user slots.
RH7/Centos7 and recent versions of fedora relocate `/*bin/*` into `/usr/*bin/`. This causes
conflicts for upgrades against xCAT-genesis-scripts-* packages which expect the `/bin` a to be
a directory while `xCAT-genesis-base-*` packages provide a link. Relocating all files into `/usr`
fixes that conflict and allows a clean upgrade from all old versions.
