vxfen

i configure vcs 2 nodes with vxfen.

more /etc/VRTSvcs/conf/config/main.cf
include "OracleASMTypes.cf"
include "types.cf"
include "CRSResource.cf"
include "CSSD.cf"
include "Db2udbTypes.cf"
include "MultiPrivNIC.cf"
include "OracleTypes.cf"
include "PrivNIC.cf"
include "RestServerTypes.cf"
include "SybaseTypes.cf"

cluster test5 (
ProtocolNumber = 11000
SecureClus = 1
UseFence = SCSI3
)

system linux-hiwv (
)

system linux-miv2 (
)

group group4 (
SystemList = { linux-hiwv = 0, linux-miv2 = 1 }
AutoStartList = { linux-hiwv }
)

DiskGroup y (
DiskGroup = y
)

Mount mnt (
MountPoint = "/y"
BlockDevice = "/dev/vx/dsk/y/y4"
FSType = vxfs
FsckOpt = "-y"
)

mnt requires y

// resource dependency tree
//
// group group4
// {
// Mount mnt
// {
// DiskGroup y
// }
// }

group vxfen (
SystemList = { linux-hiwv = 0, linux-miv2 = 1 }
AutoFailOver = 0
Parallel = 1
)

CoordPoint coordpoint (
LevelTwoMonitorFreq = 5
)

Phantom RES_phantom_vxfen (
)

// resource dependency tree
//
// group vxfen
// {
// Phantom RES_phantom_vxfen
// CoordPoint coordpoint
// }

 

Is correct in vxdisk list to see fencing disk group unimported?

vxdisk list
DEVICE TYPE DISK GROUP STATUS
aluadisk_0 auto:cdsdisk - (y4) online                   ->y4 disk coord group
aluadisk_1 auto:cdsdisk - (y4) online
aluadisk_2 auto:cdsdisk - (y4) online
aluadisk_6 auto:cdsdisk y1 y online
sda auto:none - - online invalid

Here seem that coord dg is online.

hares -state
#Resource Attribute System Value
RES_phantom_vxfen State linux-hiwv ONLINE
RES_phantom_vxfen State linux-miv2 ONLINE
coordpoint State linux-hiwv ONLINE
coordpoint State linux-miv2 ONLINE
mnt State linux-hiwv OFFLINE
mnt State linux-miv2 ONLINE
y State linux-hiwv OFFLINE
y State linux-miv2 ONLINE

    the dg with the fecing devices (by default 3 luns) should have dg auto-import flag turned off and the dg should never be imported.

    Please follow VCS admin and installation guides to set up cluster fencing.

        devices listed on /etc/vxfentab are used for cluster node fencing registration, no data is wrtitten on to these devices.

        fencing reg info is held in the disk/lun electronics.
