IOC¶

The following instructions explain the basics of starting and managing IOCs on the IOC host.

• TODO: some iocs not associated to a service, where to put?
• TODO: need to dev/prod template them too

Host¶

sls-vserv-bd-01(-dev)

Shell¶

Start up an IOC shell:

iocsh AGEBD-CPCL-MASTER_main.subs

or:

ioc shell AGEBD-CPCL-MASTER-DEV

then you can run commands to interact with EPICS.

List available PVs:

> dbl

Exit:

Ctrl + d

Install¶

For existing IOCs, a login to the IOC and a restart via ctrl+x is sufficient.

On sls-lc*

ioc install -V --ioc AGEBD-CPCL-PLAYGROUND --clean
ioc shell AGEBD-CPCL-PLAYGROUND
ctrl+x

For the initial install, additionally, the shellbox on the ioc host must be restarted.

sudo shellbox reload            # new ioc installed

Result: on ioc host, e.g. sls-vserv-bd-01-dev

vim /etc/shellbox/<port-number>

Local Tests¶

iocsh AGEBD-CPCL-PLAYGROUND_main.subs

using template file:

iocsh PLAYGROUND.template DEVICE=TEST

"Delete"¶

There is no way to really delete an IOC through the ioc cli.

What you can do: ssh sls-lc* and delete the entry from /ioc/hosts/sls-vserv-bd-01(-dev)/shellbox.conf

Restart an IOC via shellbox¶

On BD host sls-vserv-bd-01(-dev)

sudo shellbox reload            # new ioc installed
sudo shellbox status            # status of all iocs on server
sudo shellbox stop 50045        # stop ioc
sudo shellbox start 50045       # start ioc
sudo shellbox log 50045 -f      # log file (tail)
exit                            # exit ssh
