Delete a UAI

NOTE: UAI is deprecated in CSM 1.5.2 and will be removed in CSM 1.6.

There are two procedures described here. The first shows how an administrator can manually delete arbitrary UAIs or delete UAIs belonging to a given user or created using a given UAI Class. The second shows how an authorized user on can delete UAIs created in the legacy UIA creation mode.

When a UAI is deleted, any running WLM sessions associated with the owner of the UAI are left intact and can be interacted with through future UAIs owned by the same user or from UANs.

Prerequisites

For administrative procedures:

  • The administrator must be logged into an NCN or a host that has administrative access to the HPE Cray EX System API Gateway
  • The administrator must have the HPE Cray EX System CLI (cray command) installed on the above host
  • The HPE Cray EX System CLI must be configured (initialized - cray init command) to reach the HPE Cray EX System API Gateway
  • The administrator must be logged in as an administrator to the HPE Cray EX System CLI (cray auth login command)
  • The administrator must know or be able to find:
    • the name(s) of the target UAI(s) or
    • the user name of the owner of the targeted UAI(s) or
    • the class-id of the targeted UAIs

For Legacy Mode user procedures:

  • The user must be logged into a host that has user access to the HPE Cray EX System API Gateway
  • The user must have an installed initialized cray CLI and network access to the API Gateway
  • The user must have the HPE Cray EX System CLI (cray command) installed on the above host
  • The HPE Cray EX System CLI must be configured (initialized - cray init command) to reach the HPE Cray EX System API Gateway
  • The user must be logged in as to the HPE Cray EX System CLI (cray auth login command)
  • The user must know the name(s) of the target UAI(s)

Procedures

Delete UAIs as an administrator

To delete a list of UAIs as an administrator use a command of the following form:

ncn-m001-cray uas admin uais delete --uai-list UAI-NAMES

UAI-NAMES is a comma-separated list of UAI Names of targeted UAIs.

To deleted all UAIs owned by a given user, use a command of the form:

ncn-m001-cray uas admin uais delete --owner USERNAME

USERNAME is the user name of the owner of the targeted UAIs.

To delete all UAIs of a given class, use a command of the form:

ncn-m001-cray uas admin uais delete --class-id CLASS-ID

CLASS-ID is the class ID of the class used to create the targeted UAIs.

Here are some examples:

  • Delete a list of UAIs by name:

    ncn-m001-cray uas admin uais delete --uai-list uai-vers-5f46dffb,uai-vers-e530f53a
results = [ "Successfully deleted uai-vers-5f46dffb", "Successfully deleted uai-vers-e530f53a",]

  • Delete all UAIs belonging to a named user (user name here is vers):

    ncn-m001-cray uas admin uais delete --owner vers
results = [ "Successfully deleted uai-vers-5ef890be", "Successfully deleted uai-vers-da65468d",]

  • Delete all UAIs belonging to a given UAI Class:

    ncn-m001-cray uas admin uais delete --class-id a630cbda-24b4-47eb-a1f7-be1c25965ead
results = [ "Successfully deleted uai-vers-5ef890be", "Successfully deleted uai-vers-da65468d",]

Delete UAIs as an Authorized User in Legacy Mode

An authorized user in Legacy Mode can delete any UAI created by that user using a command of the form:

vers> cray uas delete --uai-list UAI-NAMES

To get a list of UAIs the user can delete:

vers> cray uas list

For example:

vers> cray uas list
[[results]]
uai_age = "0m"
uai_connect_string = "ssh vers@104.155.164.238"
uai_host = "ncn-w003"
uai_img = "registry.local/cray/cray-uai-sles15sp2:1.2.4"
uai_ip = "104.155.164.238"
uai_msg = ""
uai_name = "uai-vers-be3e219c"
uai_status = "Running: Ready"
username = "vers"

[[results]]
uai_age = "1m"
uai_connect_string = "ssh vers@34.70.243.171"
uai_host = "ncn-w001"
uai_img = "registry.local/cray/cray-uai-sles15sp2:1.2.4"
uai_ip = "34.70.243.171"
uai_msg = ""
uai_name = "uai-vers-ea57eb7b"
uai_status = "Running: Ready"
username = "vers"

To delete the UAI:

vers> cray uas delete --uai-list uai-vers-be3e219c,uai-vers-ea57eb7b

Output similar to the following is expected:

results = [ "Successfully deleted uai-vers-be3e219c", "Successfully deleted uai-vers-ea57eb7b",]
