func ExtendDevice ¶
Commands example: echo 1 > /sys/bus/scsi/drivers/sd/9:0:0:6/rescan
func FindMpathByPath ¶
Use multipath -l <path> to discover multipath device Valid <path> could be WWN or /dev/sdb like path
func FindMpathByWwn ¶
Return the multipath by wwn 1) When multipath friendly names are ON: a device file will show up in /dev/disk/by-id/dm-uuid-mpath-<WWN> /dev/disk/by-id/dm-name-mpath<N> /dev/disk/by-id/scsi-mpath<N> /dev/mapper/mpath<N>
2) When multipath friendly names are OFF: /dev/disk/by-id/dm-uuid-mpath-<WWN> /dev/disk/by-id/scsi-<WWN> /dev/mapper/<WWN>
func FindMultipathByWwn ¶
func FlushDeviceIO ¶
path = "/dev/sdb" or " "/dev/disk/by-path/ip-10.244.213.177:3260-iscsi-iqn.1992-04.com.emc:cx.fnm00150600267.a0-lun-10"
func GetDeviceInfo ¶
func GetDeviceInfo(path string) (model.DeviceInfo, error)
output: sudo sg_scan /dev/disk/by-path/pci-0000:05:00.1-fc-0x5006016d09200925-lun-0 /dev/disk/by-path/pci-0000:05:00.1-fc-0x5006016d09200925-lun-0: scsi9 channel=0 id=0 lun=0 [em]
func IsFCDevice ¶
func IsFCSupport ¶
func IsFCSupport() bool
func IsMultipathEnabled ¶
func IsMultipathEnabled() bool
func RemoveSCSIDevice ¶
func RemoveSCSIDevice(path string)
path = "/dev/sdb" or "sdb" Use echo 1 > /sys/block/%s/device/delete to force delete the device
func RescanHosts ¶
Do a more specific scan instead of a wildcard
func ResizeMpath ¶
func ScanSCSIBus ¶
use echo "c t l" > to /sys/class/scsi_host/%s/scan
func SetExecutor ¶
