This package is used for go codes to get MegaRaid stat.
At first, you need install MegaRAID in your servers.
Create a DiskStatus struct by calling diskutil.NewDiskStatus(). You need provide the MegaCli binary path and the count of RAID card in your server.
ds, err := diskutil.NewDiskStatus(megaPath, adapterCount)
if err != nil {
fmt.Fprintf(os.Stderr, "DiskStatus New error: %v\n", err)
return
}
err = ds.Get()
if err != nil {
fmt.Fprintf(os.Stderr, "DiskStatus Get error: %v\n", err)
return
}
fmt.Println(ds)
After calling Get(), you can visit any stat in the DiskStatus like this:
for i, ads := range ds.AdapterStats {
fmt.Printf("adapter #%d \n", i)
for j, pds := range ads.PhysicalDriveStats {
pdStatus := pds.FirmwareState
pdName := []string{pds.Brand, pds.Model, pds.SerialNumber}
pdSN := strings.Join(pdName, " ")
fmt.Printf("PD%d: %s status: %s\n", j, pdSN, pdStatus)
}
fmt.Printf("\n")
}
If you focus on the disk which is broken, you can use ListBrokenDrive() to get them:
brokenVds, brokenPds, err := ds.ListBrokenDrive()
if err != nil {
fmt.Fprintf(os.Stderr, "DiskStatus ListBrokenDrive error: %v\n", err)
return
}
for _, bvd := range brokenVds {
fmt.Println(bvd)
}
for _, bpd := range brokenPds {
fmt.Println(bpd)
}
Or you can print the DiskStatus in json format by calling ToJson():
jsonStatus, err := ds.ToJson()
if err != nil {
fmt.Fprintf(os.Stderr, "DiskStatus ToJson error: %v\n", err)
return
}
fmt.Println(jsonStatus)
