[LU-8610] Better handle of HW dependency of DLC configuration

• Type: Bug
• Resolution: Unresolved
• Priority: Minor
• Affects Version/s: Lustre 2.9.0
• Environment: Any DLC setup with changing CPT partition setup.
• Severity: 3
• Assignee: Amir Shehata (Inactive)
• Reporter: James A Simmons

Description

While testing LU-5050 the old configuration for my DLC stopped working and it reported the error:

[771343.391364] LustreError: 138538:0:(libcfs_string.c:466:cfs_expr_list_values()) Number of values 4 exceeds max allowed 16 [771343.391507] LNetError: 138538:0:(config.c:172:lnet_ni_alloc()) Failed to set CPTs for NI o2ib1: -22

Which is not clear what is wrong.
