Hello List,
what is the preferred way to power control nodes? IPMI setup is done by qluman, but there does not seem to be a way to control nodes from the GUI. I've found ql-remote-control, but it complains about a missing config file, and I did not find an example file to explain its syntax.
Thanks,
A.

currently Qlustar/QluMan just configures the IPMI interface's IP automatically and registers it including its hostname (<node>-ipmi per default) with NIS. For power control you have two options:
a) Just use ipmipower from the cmd line. b) Create a custom command with the RXEngine, e.g.
Example command to be entered in the command editor (substitute <user>/<pwd>):
--------------------------------------------------------- hostlist="$(hostlist-expand %1)" for host in $hostlist; do ipmipower -h $host-ipmi -u $<user> -p <pwd> --cycle done ---------------------------------------------------------
Make sure you select 'Headnode' as the 'Execute on:' option.
Hope that helps.
Best,
Roland
Hi,

Certainly a possibility, but a more integrated solution does have its advantages.
b) Create a custom command with the RXEngine, e.g.
OK, I'll try that.
Thanks!

Hi,

Hmm. The hostname is there, but the interfaces are not configured -- they still carry their old IPs. I guess I'll have to investigate what goes wrong. Where is the configuration implemented? Are there any logs?
Thanks,

I guess you didn't set the generic property 'Initialize IPMI' (see https://docs.qlustar.com/en-US/Qlustar_Cluster_OS/10.1/html-single/QluMan_Gu... )

Indeed. Fixed that now, but the nodes won't boot because of some error accessing the database. I'll investigate next week.
Thanks,
