Pertaining to: LCLSECSD-923 - Getting issue details... STATUS .


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 (subnet cds-lfe.pcsdn) which runs four other IOCs:

  • ioc-xrt-mecpim1-ims [ioc/xrt/ims/R2.2.10]
  • ioc-xrt-mec-xfls-ims [ioc/xrt/ims/R6.0.2]
  • 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.

Cann you also call out the digi/moza channels used and what else iis located on that terminal server?
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,.
