Restart all the volumes in each disk group:
# vxvol -g diskgroup startall
The output from the vxdisk list command now shows DMP metanode names
according to the current naming scheme. For example, under the default or
legacy naming scheme, vxdisk list displays the devices as:
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
c2t0d0 auto:LVM - - LVM
c3t2d0 auto:LVM - - LVM
c89t0d0 auto:cdsdisk - - online
c89t0d1 auto:cdsdisk - - online
c89t0d2 auto:cdsdisk - - online
c89t0d3 auto:cdsdisk - - online
c89t0d4 auto:cdsdisk - - online
c89t0d5 auto:cdsdisk - - online
Under the new naming scheme, vxdisk list displays the devices as:shown.
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
disk155 auto:LVM - - LVM
disk156 auto:LVM - - LVM
disk224 auto:cdsdisk - - online
disk225 auto:cdsdisk - - online
disk226 auto:cdsdisk - - online
disk227 auto:cdsdisk - - online
disk228 auto:cdsdisk - - online
disk229 auto:cdsdisk - - online
See “Changing the disk-naming scheme” on page 98.
DMP in a clustered environment
Note: You need an additional license to use the cluster feature of VxVM.
In a clustered environment where Active/Passive type disk arrays are shared by
multiple hosts, all nodes in the cluster must access the disk via the same physical
storage controller port. Accessing a disk via multiple paths simultaneously can
severely degrade I/O performance (sometimes referred to as the ping-pong effect).
