Pertaining to:
.Jira server SLAC National Accelerator Laboratory serverId 1b8dc293-975d-3f2d-b988-18fd9aec1546 key LCLSECSD-923
...
The MEC attenuators are controlled by IOC ioc-xrt-mecppatt-ims
...
running ioc/xrt/ims/R2.2.9
...
. The host machine for this ioc is the RHEL5 Supermicro Atom ioc-xrt-mec-mot1
...
(B960 XRT R04 E39; subnet cds-lfe.pcsdn) which runs four other IOCs:
- ioc-xrt-mec- mecpim1
- xfls-ims [ioc/xrt/ims/R2.2.10]
- ioc-xrt- mec-xfls-ims [ioc/xrt/ims/R6.0.2]
- mecpims1-ims
- ioc-xrt-m3h-switch [ioc/mec/m3h_switch/R1.0.0]
- ioc-mec-pulsepicker-ims [ioc/common/pulsepicker/R1.1.7]
serverStat does not report any additional hardware interfaces beyond ethernet.
...
Notes from Silke:
- The pulse picker may be complicated: the 3 PP devices in the XRT do share some physical setup.
- As all IOCs on that server are ethernet only, one can decide to move IOCs temporarily if needed (either move the attenuator or the pulse picker).
What does m3h-switch do?
Looking into channels.
In re: m3h_switch (dated from 9 July 2013; engineer jyin)
It's pulling in information from PVs that are clearly not on the MEC subnet,.
m3h_switch.db
record(m3h, "XRT:M3H:SWITCH")
...
The database in ioc-xrt-m3h-switch just contains links to other PVs found on the cds-lfe.pcdsn subnet:
- HXX:HXM:MMS01:*
- IOC: ioc-xrt-hxx-hxm-pim01-ims
- Host: ioc-xrt-rec01cds-lfe.pcsdn
- CXI:R48:EVR:41:
...
- *
- IOC: ioc-xrt-cxi-picker
- Hard RTEMS IOC
- HFX:DG2:STP:01
...
- :*
- IOC: ioc-xcs-stoppers
- Host: ioc-xrt-vacuum
- PATT:SYS0:1:*
- IOC: ioc-det-evg-fake, ioc-mec-evg-fake
These IOCs make use of a digi and a moxa. Switch swh-lfe-xrt is located at B960 XRT R02 E40 B.
