You can use the API to apply a system patch on vRealize Suite Lifecycle Manager.

To apply a system patch that patches vRealize Suite Lifecycle Manager, you first create a snapshot of the current vRealize Suite Lifecycle Manager appliance. Then you obtain the system patch ID and apply the patch.

Prerequisites

Procedure

  1. Log in to the vCenter to take a snapshot of the vRealize Suite Lifecycle Manager appliance. You can use this snapshot to perform a rollback if a failure occurs during patching.
  2. List the patches. 
    curl -X GET \
  '$url/lcm/lcops/api/v2/settings/patch-binaries' \
  -H 'Authorization: Basic YWRtaW5AbG9jYWw6VGhpc0lzUGFzc3dvcmQ=' \
  -H 'Content-Type: application/json' | jq "."
    Check the response to find a system patch that is downloaded and available to apply. A snippet of the response shows the patch ID and "patchDownloadStatus": "DOWNLOAD".

  3. Assign the patch ID variable for the system patch. 
    syspatchId = "d5b90274-3906-43b8-8eb3-7f73e76c2iu9"
  4. Apply the system patch. 
    curl -X POST \
  '$url/lcm/lcops/api/v2/system-patch/$syspatchId' \
  -H 'Authorization: Basic YWRtaW5AbG9jYWw6VGhpc0lzUGFzc3dvcmQ=' \
  -H 'Content-Type: application/json' \
 | jq "."
    The request triggers the API. The response shows the request ID. 
    {
    "requestId":"poiu5678a-6e1f-4772-a97d-af300ad8888c"
}
  5. Assign the request ID variable. 
    requestId = "poiu5678a-6e1f-4772-a97d-af300ad8888c"
  6. vRealize Suite Lifecycle Manager services are not reachable while the patch is applied, so wait approximately ten minutes before polling the request. 
    curl -X GET '$url /lcm/request/api/v2/requests/$requestId' -H 'Authorization: Basic YWRtaW5AbG9jYWw6VGhpc0lzUGFzc3dvcmQ=' | jq "."
    After completion, the system patch is applied.
