Check huawei-dorado-host

Overview

Batch querying basic information about hosts attached to a Huawei OceanStor Dorado storage system via the REST Interface, using the https://${ip}:${port}/deviceManager/rest/${deviceId}/host endpoint. Cookies and iBaseTokens are stored and re-used (the session timeout period is usually 20 minutes).

Hints:

  • Tested on Huawei OceanStor Dorado 8000 V6 6.1.0.

  • Create a read-only API user that can perform query only.

  • Sometimes the API returns This operation fails to be performed because of the unauthorized REST. Before performing this operation, ensure that REST is authorized., although everything is fine. In this case, the check simply tries to retrieve the data again, a maximum of 9 times within 9 seconds.
