Veritas Volume Manager question (Disk layout with 4 plexes)
I am trying to build a veritas volume similar to an existing volume on another server. The output on source server is:
Code:
usbtor12# vxprint -hrtg appdg
v anvil_sqlVOL - ENABLED ACTIVE 629145600 SELECT - fsgen
pl anvil_sqlVOL-01 anvil_sqlVOL ENABLED ACTIVE 629145600 CONCAT - RW
sd uspv100_lun0-02 anvil_sqlVOL-01 uspv100_lun0 20971520 629145600 0 c1t71d0 ENA
pl anvil_sqlVOL-02 anvil_sqlVOL ENABLED ACTIVE 629145600 CONCAT - RW
sd uspv300_lun0-01 anvil_sqlVOL-02 uspv300_lun0 0 629145600 0 c1t73d0 ENA
pl anvil_sqlVOL-03 anvil_sqlVOL ENABLED ACTIVE LOGONLY CONCAT - RW
sd uspv100_lun0-01 anvil_sqlVOL-03 uspv100_lun0 0 2112 LOG c1t71d0 ENA
pl anvil_sqlVOL-04 anvil_sqlVOL ENABLED ACTIVE LOGONLY CONCAT - RW
sd uspv300_lun0-02 anvil_sqlVOL-04 uspv300_lun0 629145600 2112 LOG c1t73d0 ENA
This volume is on diskgroup 'appdg' (both are 400gb LUN's):
Code:
usbtor12# vxdisk -g appdg list
DEVICE TYPE DISK GROUP STATUS
c1t71d0s2 auto:cdsdisk uspv100_lun0 appdg online
c1t73d0s2 auto:cdsdisk uspv300_lun0 appdg online
When I created the volume on the target server with similar LUN size (using the command: #vxassist -g appdg make anvil_sqlVOL 300g),
I see the volume as :
Code:
usbmon59# vxprint -hrtg appdg
dg appdg default default 23000 1264089847.10.sbpsvrwm289
dm uspv100_lun0 c4t71d0s2 auto 65536 858189568 -
dm uspv300_lun0 c4t73d0s2 auto 65536 858189568 -
v anvil_sqlVOL - ENABLED ACTIVE 629145600 SELECT - fsgen
pl anvil_sqlVOL-01 anvil_sqlVOL ENABLED ACTIVE 629145600 CONCAT - RW
sd c4t71d0-01 anvil_sqlVOL-01 uspv100_lun0 0 629145600 0 c4t71d0 ENA
pl anvil_sqlVOL-02 anvil_sqlVOL ENABLED ACTIVE 629145600 CONCAT - RW
sd uspv300_lun0-01 anvil_sqlVOL-02 uspv300_lun0 0 629145600 0 c4t73d0 ENA
I also tried to create another test volume with layout=mirroring, but did not work:
Code:
# vxassist -g appdg make testVOL 5g layout=mirror
The output is still the same - volume with 2, not 4 plexes
Code:
usbmon59# vxprint -hrtg appdg
dg appdg default default 23000 1264089847.10.sbpsvrwm289
dm uspv100_lun0 c4t71d0s2 auto 65536 858189568 -
dm uspv300_lun0 c4t73d0s2 auto 65536 858189568 -
v anvil_sqlVOL - ENABLED ACTIVE 629145600 SELECT - fsgen
pl anvil_sqlVOL-01 anvil_sqlVOL ENABLED ACTIVE 629145600 CONCAT - RW
sd c4t71d0-01 anvil_sqlVOL-01 uspv100_lun0 0 629145600 0 c4t71d0 ENA
pl anvil_sqlVOL-02 anvil_sqlVOL ENABLED ACTIVE 629145600 CONCAT - RW
sd uspv300_lun0-01 anvil_sqlVOL-02 uspv300_lun0 0 629145600 0 c4t73d0 ENA
v testVOL - ENABLED ACTIVE 10485760 SELECT - fsgen
pl testVOL-01 testVOL ENABLED ACTIVE 10485760 CONCAT - RW
sd uspv100_lun0-01 testVOL-01 uspv100_lun0 629145600 10485760 0 c4t71d0 ENA
pl testVOL-02 testVOL ENABLED ACTIVE 10485760 CONCAT - RW
sd uspv300_lun0-02 testVOL-02 uspv300_lun0 629145600 10485760 0 c4t73d0 ENA
Any idea how can I create the same volume with 4 plexes.
Thanks
