When the Boot Orchestration Agent (BOA), an agent of the Boot Orchestration Service (BOS), encounters a failure, it issues a command to rerun the operation for any nodes that experienced the failure. However, the syntax of this command is faulty.
The faulty command includes squiggly braces around a comma separated list of quoted nodes. These squiggly braces, single quotes, and the spaces separating the individual nodes all need to be removed. Then, this reformatted command can be run.
Example of a faulty command in the BOA log:
ERROR - cray.boa.agent - You can attempt to boot these nodes by issuing the command:
cray bos v1 session create --template-uuid shasta-1.4-csm-bare-bones-image --operation boot --limit {'x3000c0s25b3n0', 'x3000c0s23b4n0', 'x3000c0s20b4n0', 'x3000c0s37b2n0', 'x1000c0s7b0n0', 'x1000c3s3b0n0', 'x1000c1s1b1n1', 'x1000c0s7b1n0', 'x1000c2s3b1n1', 'x3000c0s20b3n0', 'x3000c0s25b1n0', 'x3000c0s20b1n0', 'x3000c0s20b2n0', 'x3000c0s25b2n0', 'x3000c0s23b3n0', 'x3000c0s25b4n0', 'x1000c1s1b1n0', 'x3000c0s37b1n0', 'x3000c0s37b4n0', 'x1000c2s3b1n0', 'x3000c0s23b2n0', 'x3000c0s23b1n0', 'x1000c0s7b1n1', 'x3000c0s37b3n0', 'x1000c0s7b0n1'}
Example of the correct command:
cray bos v1 session create --template-uuid shasta-1.4-csm-bare-bones-image --operation boot --limit x3000c0s25b3n0,x3000c0s23b4n0,x3000c0s20b4n0,x3000c0s37b2n0,x1000c0s7b0n0,x1000c3s3b0n0,x1000c1s1b1n1,x1000c0s7b1n0,x1000c2s3b1n1,x3000c0s20b3n0,x3000c0s25b1n0,x3000c0s20b1n0,x3000c0s20b2n0,x3000c0s25b2n0,x3000c0s23b3n0,x3000c0s25b4n0,x1000c1s1b1n0,x3000c0s37b1n0,x3000c0s37b4n0,x1000c2s3b1n0,x3000c0s23b2n0,x3000c0s23b1n0,x1000c0s7b1n1,x3000c0s37b3n0,x1000c0s7b0n1
Cut and paste the faulty command and assign to an environment variable.
linux# CMD="cray bos v1 session create --template-uuid shasta-1.4-csm-bare-bones-image --operation boot --limit {'x3000c0s25b3n0', 'x3000c0s23b4n0', 'x3000c0s20b4n0', 'x3000c0s37b2n0', 'x1000c0s7b0n0', 'x1000c3s3b0n0', 'x1000c1s1b1n1', 'x1000c0s7b1n0', 'x1000c2s3b1n1', 'x3000c0s20\
b3n0', 'x3000c0s25b1n0', 'x3000c0s20b1n0', 'x3000c0s20b2n0', 'x3000c0s25b2n0', 'x3000c0s23b3n0', 'x3000c0s25b4n0', 'x1000c1s1b1n0', 'x3000c0s37b1n0', 'x3000c0s37b4n0', 'x1000c2s3b1n0', 'x3000c0s23b2n0', 'x3000c0s23b1n0', 'x1000c0s7b1n1', 'x3000c0s37b3n0', 'x1000c0s7b0n\
1'}"
Then, paste this command to get the corrected output.
