SCSI boot fail on z17

[takeosbzk-debug]

Describe the bug
When we use "scsi-load" to boot Linux with "--disk-partition-id" option, this option doesn't work on z17.
There is no problem when a system boots on z15 by zhmccli.
I think z17 has new option "Boot program sector - Automatic" on SCSI Load HMC menu, but scsi-load webapi doesn't have this option.

To Reproduce
Next command fail on z17 but success on z15
zhmc -n -h $hmc_ip_addr $logon_str_z15 lpar scsi-load $sub_cec_name $sub_lpar_name $load_addr $load_wwpn $load_lun --disk-partition-id $boot_pgm

Expected behavior
Success boot on z17

@takeosbzk-debug Hello. Thanks for reporting this. It should actually be in the zhmccli repo, but let's continue discussing it here.

Can you please turn on logging and send us the resulting log that contains the interactions with the HMC? We need that to determine whether it is a bug in the zhmc command or a defect in the HMC itself.

E.g. --log hmc=debug --log-dest file.log

I uploaded 3 files.

I tried to add a new web api function "load-program" to zhmccli and zhmcclient .
I succeeded to boot from scsi with boot program selector by using "load-program" function.
I hope to support a web api "load-program" officially.
