All-Volumes Query Errors
Upon an unsuccessful query of all volumes, the INT_SERV_ERR might be returned. For details
about this error code, see Table 5 (page 22). For generic API error codes, see Table 5 (page 22).
Chunking Errors
During a query for all volumes or all VLUNs, the WSAPI server might encounter either of the
following errors related to chunked encoding:
• An error might occur when the WSAPI server tries to get the first chunk of data. In this case,
the WSAPI sends the HTTP error to the client, and stops sending the subsequent chunks of
data. For example:
HTTP/1.1 <http error code> <http error msg>

}
• An error may occur while the WSAPI tries to get the second or any subsequent chunk of data.
Once HTTP headers are sent to the client (a header is always sent with the first successful
chunk of data), the intended response must finish being sent. If an error occurs midway through
