Unity REST API hostAccess

Question

Hi everyone, I'm trying to script LUN creation for Unity 500 with the REST API, but i have some issue with hostAccess configuration. I tried to follow the apidocs on the https://unity_ip/apidocs/ but i think i missed how this api work. I can create a simple LUN with : my $body = '{'name':''.$lun_name.'','lunParameters':{'pool':{'id':'pool_2'},'size':'.$lun_size.','isThinEnabled':'false'}}'; $client->POST('/api/types/storageResource/action/createLun', $body); But when i want to add the hostAccess configuration i have this following error : 'httpStatusCode':422,'messages':[{'en-US':'The LUN or consistency group host access parameter is invalid. (Error Code:0x6701026)'}] The body request was : my $body = '{'name':''.$lun_name.'','lunParameters':{'pool':{'id':'pool_2'},'size':'.$lun_size.','isThinEnabled':'false','hostAccess':[{'host':{'id':'Host_6'}}]}}'; Thanks for your help

I think you need to include the 'accessMask' in your 'hostAccess' .  So for a production access to a LUN you would need: my $body = '{'name':''.$lun_name.'','lunParameters':{'pool':{'id':'pool_2'},'size':'.$lun_size.','isThinEnabled':'false','hostAccess':[{'host':{'id': 'Host_6'},'accessMask': 1}]}}';

Hi,

It's looks like the attriube accesMask was required.

Everything works fine with this body configuration

{

"name":"TEST226",

"lunParameters":{

"pool":{"id":"pool_2"},

"size":"10000000000",

"isThinEnabled":"false",

"hostAccess":[{

"host":{"id":"Host_6"},

"accessMask":"1"}

]

}

Now, i have a similar issue with HLU modification : /api/instances/host/Host_6/action/modifyHostLUNs

i use this body, but this is not working :

{

"hostLunModifyList":{

"hostLUN":{

"id": "Host_6_sv_33_prod"

},

"hlu":"10"

}

What's wrong with this ?

How to identify the required parameter ?
