REST API response error

[raysa123]

Hi,

Is anyone can see what is the problem when I trying to execute the curl command to get the CPG's on the Primera storage?  Got the key from successful POST method using my user and password as Header then when i try to use the key to get the CPG's info I got invalid session key. 

% showwsapi
-Service- -State- HTTPS_Port -Version- ----------API_URL----------
Enabled Active 443 1.10.0 https://PRIMERA_IPADDRESS/api/v1

See curl command and error below:

curl -k -i -X GET -H "X-HP3PAR-WSAPI-SessionKey: 0-eb6507cde8a2fb82cc579ce1a5d55398-2a1ce167" \

thanks but still could not get what is wrong in my syntax above as I am using the latest key generated using put method. the documentation is for HPE XP still confusing to me.

Is there any idea on what will be the correct syntax base on my error above?

Hi Raysa123,

I assume, the correct session key is used.
curl -k -H 'Content-Type:application/json' --data '{ "user":"username" ,"password":"user_password"}' -X POST https://<array ip>/api/v1/credentials {"key":"0-5a2d2c9b9ec72c42c5dd0cf1b544c226-19dec165"}

Fetch the session key from above output and use it with the key name " X-HP3PAR-WSAPI-SessionKey "

Try the below command:

curl -ki https://PRIMERA_IPADDRESS/api/v1/cpgs X GET -H "X-HP3PAR-WSAPI-SessionKey":"<session key from above output>"

Hi @veeyarvi ,

You provide the right syntax! thanks a lot for sharing.

By the way is it possible to fetch or query a specific key to display the value from the response body? For example i want to monitor only the Primera system "freeCapacityMiB" from the output of this endpoint "/api/v1/system'. Hope you could extend your kindness for a little more if you know something about it.

below is my example result  using this endpoint  "/api/v1/system'.

curl -k https://<not revealing IPAddr>/api/v1/system?query="name" -X GET -H "X-HP3PAR-WSAPI-SessionKey":"0-f288cbcf927e53fa0ccd9a4afd41ae6b-7feee367"
{"code":9,"desc":"unsupported operation for the resource"}

Hi Raysa321,

I do not think 'freeCapacityMiB' is a supported one. As per Success | HPE Alletra 9000: Web Services API v1.10 developer reference , I could see 'freeMiB' and 'freeInitializedMiB' might be the one you are looking for (as per requirement).

Hi @vveeyarvi,

would you help what is the correct query? i tried it the one i showed above but it returns an error.

[veeyarvi]

Hi Raysa,

The below will list the complete endpoint

key=$(curl -k -H 'Content-Type:application/json' --data '{ "user":"username" ,"password":"password"}' -X POST IP address/api/v1/credentials | jq -r '.key'); curl -k -H "Accept:application/json" -H "Content-Type:application/json" -H "X-HP3PAR-WSAPI-SessionKey":"$key" IP Address/api/v1/system | jq -r

I think jq has options to fileter the required output (only) but I am yet to explore that option.
