My blog entry, Fujitsu PRIMERGY: Configuring RAID via iRMC REST API, explains how to use iRMC REST API to configure logical drives with the supported RAID cards. The JSON file I showed in my blog post as an example should work for all supported Fujitsu RAID cards. However, in my experience, it may not work with PRAID CP400i.
When I performed a RAID 0 logical drive creation with four HDDs under PRAID CP400i on RX4770 M2 or RX2530 M4 using the following JSON file, it failed with an error ("input parameters are invalid") even though it worked fine with other RAID cards like PRAID EP400i:
{
"Server":{
"HWConfigurationIrmc":{
"@Processing":"execute",

"RAIDAdapter":[
{
"@AdapterId":"RAIDAdapter0",
"@ConfigurationType":"Addressing",
"Arrays":{
"Array":[
{
"@Number":0,
"@ConfigurationType":"Setting",
"PhysicalDiskRefs":{
"PhysicalDiskRef":[
{
"@Number":"0"
},
{
"@Number":"1"
},
{
"@Number":"2"
},
{
"@Number":"3"
}
]
}
}
]
},
"LogicalDrives":{
"LogicalDrive":[
{
"@Number":0,
"@Action":"Create",
"RaidLevel":"0",

"ArrayRef":[
{
"@Number":0
}
]
}
}
]
}
}
]
},
"@Version":"1.00"
},
"@Version":"1.01"
}
}
Here is the session log with the error.

With some trial-and-error experiments, I found out that the Stripe parameter was needed in order for the above mentioned JSON file to work with PRAID CP400i. Below is the one that worked for PRAID CP400i.
{
"Server":{
"HWConfigurationIrmc":{
"@Processing":"execute",
"Adapters":{
"RAIDAdapter":[
{
"@AdapterId":"RAIDAdapter0",
"@ConfigurationType":"Addressing",
"Arrays":{
"Array":[
{
"@Number":0,
"@ConfigurationType":"Setting",
"PhysicalDiskRefs":{
"PhysicalDiskRef":[
{
"@Number":"0"
},
{
"@Number":"1"
},
{
"@Number":"2"
},
{
"@Number":"3"
}
]
}
}
]
},
"LogicalDrives":{
"LogicalDrive":[
{
"@Number":0,
"@Action":"Create",
"RaidLevel":"0",
"ArrayRefs":{
"ArrayRef":[
{
"@Number":0
}
]
},
"Stripe":{
"@Unit":"KB",
"#text":64
}
}
]
}
}
]
},
"@Version":"1.00"
},
"@Version":"1.01"
}
}
As you can see, the only different is the Stripe parameter for the logical drive.
