The following examples show use and require constraints for storage allocation.
Example 1 - require constraint
This example shows the require constraint in a disk group that has disks from two arrays: emc_clariion0 and ams_wms0. Both arrays are connected through the same HBA hostportid (06-08-02), but the arrays have different arraytype (A/A and A/A-A respectively).
The following output shows the disk group information:
# vxprint -g testdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg testdg testdg - - - - - - dm ams_wms0_359 ams_wms0_359 - 2027264 - - - - dm ams_wms0_360 ams_wms0_360 - 2027264 - - - - dm ams_wms0_361 ams_wms0_361 - 2027264 - - - - dm ams_wms0_362 ams_wms0_362 - 2027264 - - - - dm emc_clariion0_0 emc_clariion0_0 - 4120320 - - - - dm emc_clariion0_1 emc_clariion0_1 - 4120320 - - - - dm emc_clariion0_2 emc_clariion0_2 - 4120320 - - - - dm emc_clariion0_3 emc_clariion0_3 - 4120320 - - - -
To allocate both the data and the log on the disks that are attached to the particular HBA and that have the array type A/A:
# vxassist -g testdg make v1 1G logtype=dco dcoversion=20 \ require=hostportid:06-08-02,arraytype:A/A
The following output shows the results of the above command. The command allocated disk space for the data and the log on emc_clariion0 array disks, which satisfy all the storage specifications in the require constraint:
# vxprint -g testdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg testdg testdg - - - - - - dm ams_wms0_359 ams_wms0_359 - 2027264 - - - - dm ams_wms0_360 ams_wms0_360 - 2027264 - - - - dm ams_wms0_361 ams_wms0_361 - 2027264 - - - - dm ams_wms0_362 ams_wms0_362 - 2027264 - - - - dm emc_clariion0_0 emc_clariion0_0 - 4120320 - - - - dm emc_clariion0_1 emc_clariion0_1 - 4120320 - - - - dm emc_clariion0_2 emc_clariion0_2 - 4120320 - - - - dm emc_clariion0_3 emc_clariion0_3 - 4120320 - - - - v v1 fsgen ENABLED 2097152 - ACTIVE - - pl v1-01 v1 ENABLED 2097152 - ACTIVE - - sd emc_clariion0_0-01 v1-01 ENABLED 2097152 0 - - - dc v1_dco v1 - - - - - - v v1_dcl gen ENABLED 67840 - ACTIVE - - pl v1_dcl-01 v1_dcl ENABLED 67840 - ACTIVE - - sd emc_clariion0_0-02 v1_dcl-01 ENABLED 67840 0 - - -
Example 2 - use constraint
This example shows the use constraint in a disk group that has disks from three arrays: ams_wms0, emc_clariion0, and hitachi_vsp0.
The following output shows the disk group information:
# vxprint -g testdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg testdg testdg - - - - - - dm ams_wms0_359 ams_wms0_359 - 2027264 - - - - dm ams_wms0_360 ams_wms0_360 - 2027264 - - - - dm ams_wms0_361 ams_wms0_361 - 2027264 - - - - dm ams_wms0_362 ams_wms0_362 - 2027264 - - - - dm emc_clariion0_0 emc_clariion0_0 - 4120320 - - - - dm hitachi_vsp0_3 hitachi_vsp0_3 - 4120320 - - - -
To allocate both the data and the log on the disks that belong to the array ams_wms0 or the array emc_clariion0:
# vxassist -g testdg make v1 3G logtype=dco dcoversion=20 \ use=array:ams_wms0,array:emc_clariion0
The following output shows the results of the above command. The command allocated disk space for the data and the log on disks that satisfy the arrays specified in the use constraint.
# vxprint -g testdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg testdg testdg - - - - - - dm ams_wms0_359 ams_wms0_359 - 2027264 - - - - dm ams_wms0_360 ams_wms0_360 - 2027264 - - - - dm ams_wms0_361 ams_wms0_361 - 2027264 - - - - dm ams_wms0_362 ams_wms0_362 - 2027264 - - - - dm emc_clariion0_0 emc_clariion0_0 - 4120320 - - - - dm hitachi_vsp0_3 hitachi_vsp0_3 - 4120320 - - - - v v1 fsgen ENABLED 6291456 - ACTIVE - - pl v1-01 v1 ENABLED 6291456 - ACTIVE - - sd ams_wms0_359-01 v1-01 ENABLED 2027264 0 - - - sd ams_wms0_360-01 v1-01 ENABLED 143872 2027264 - - - sd emc_clariion0_0-01 v1-01 ENABLED 4120320 2171136 - - - dc v1_dco v1 - - - - - - v v1_dcl gen ENABLED 67840 - ACTIVE - - pl v1_dcl-01 v1_dcl ENABLED 67840 - ACTIVE - - sd ams_wms0_360-02 v1_dcl-01 ENABLED 67840 0 - - -
Example 3: datause and logrequire combination
This example shows the combination of a datause constraint and a logrequire constraint. The disk group has disks from three arrays: ams_wms0, emc_clariion0, and hitachi_vsp0, which have different array types.
The following output shows the disk group information:
# vxprint -g testdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg testdg testdg - - - - - - dm ams_wms0_359 ams_wms0_359 - 2027264 - - - - dm ams_wms0_360 ams_wms0_360 - 2027264 - - - - dm ams_wms0_361 ams_wms0_361 - 2027264 - - - - dm ams_wms0_362 ams_wms0_362 - 2027264 - - - - dm emc_clariion0_0 emc_clariion0_0 - 4120320 - - - - dm emc_clariion0_1 emc_clariion0_1 - 4120320 - - - - dm emc_clariion0_2 emc_clariion0_2 - 4120320 - - - - dm emc_clariion0_3 emc_clariion0_3 - 4120320 - - - - dm hitachi_vsp0_3 hitachi_vsp0_3 - 4120320 - - - -
To allocate data on disks from ams_wms0 or emc_clariion0 array, and to allocate log on disks from arraytype A/A-A:
# vxassist -g testdg make v1 1G logtype=dco dcoversion=20 \ datause=array:ams_wms0,array:emc_clariion0 logrequire=arraytype:A/A-A
The following output shows the results of the above command. The command allocated disk space for the data and the log independently. The data space is allocated on emc_clariion0 disks that satisfy the datause constraint. The log space is allocated on ams_wms0 disks that are A/A-A arraytype and that satisfy the logrequire constraint:
# vxprint -g testdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg testdg testdg - - - - - - dm ams_wms0_359 ams_wms0_359 - 2027264 - - - - dm ams_wms0_360 ams_wms0_360 - 2027264 - - - - dm ams_wms0_361 ams_wms0_361 - 2027264 - - - - dm ams_wms0_362 ams_wms0_362 - 2027264 - - - - dm emc_clariion0_0 emc_clariion0_0 - 4120320 - - - - dm emc_clariion0_1 emc_clariion0_1 - 4120320 - - - - dm emc_clariion0_2 emc_clariion0_2 - 4120320 - - - - dm emc_clariion0_3 emc_clariion0_3 - 4120320 - - - - dm hitachi_vsp0_3 hitachi_vsp0_3 - 4120320 - - - - v v1 fsgen ENABLED 2097152 - ACTIVE - - pl v1-01 v1 ENABLED 2097152 - ACTIVE - - sd emc_clariion0_0-01 v1-01 ENABLED 2097152 0 - - - dc v1_dco v1 - - - - - - v v1_dcl gen ENABLED 67840 - ACTIVE - - pl v1_dcl-01 v1_dcl ENABLED 67840 - ACTIVE - - sd ams_wms0_359-01 v1_dcl-01 ENABLED 67840 0 - - -
Example 4 - use and require combination
This example shows the combination of a use constraint and a require constraint. The disk group has disks from three arrays: ams_wms0, emc_clariion0, and hitachi_vsp0. Only the disks from ams_wms0 array are multi-pathed.
The following output shows the disk group information:
# vxprint -g testdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg testdg testdg - - - - - - dm ams_wms0_359 ams_wms0_359 - 2027264 - - - - dm ams_wms0_360 ams_wms0_360 - 2027264 - - - - dm ams_wms0_361 ams_wms0_361 - 2027264 - - - - dm ams_wms0_362 ams_wms0_362 - 2027264 - - - - dm emc_clariion0_0 emc_clariion0_0 - 4120320 - - - - dm emc_clariion0_1 emc_clariion0_1 - 4120320 - - - - dm emc_clariion0_2 emc_clariion0_2 - 4120320 - - - - dm emc_clariion0_3 emc_clariion0_3 - 4120320 - - - - dm hitachi_vsp0_3 hitachi_vsp0_3 - 4120320 - - - -
To allocate data and log space on disks from emc_clariion0 or ams_wms0 array, and disks that are multi-pathed:
# vxassist -g testdg make v1 1G logtype=dco dcoversion=20 \ use=array:emc_clariion0,array:ams_wms0 require=multipathed:yes
The following output shows the results of the allocation. The data and log space is on ams_wms0 disks, which satisfy the use as well as the require constraints:
# vxprint -g testdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg testdg testdg - - - - - - dm ams_wms0_359 ams_wms0_359 - 2027264 - - - - dm ams_wms0_360 ams_wms0_360 - 2027264 - - - - dm ams_wms0_361 ams_wms0_361 - 2027264 - - - - dm ams_wms0_362 ams_wms0_362 - 2027264 - - - - dm emc_clariion0_0 emc_clariion0_0 - 4120320 - - - - dm emc_clariion0_1 emc_clariion0_1 - 4120320 - - - - dm emc_clariion0_2 emc_clariion0_2 - 4120320 - - - - dm emc_clariion0_3 emc_clariion0_3 - 4120320 - - - - dm hitachi_vsp0_3 hitachi_vsp0_3 - 4120320 - - - - v v1 fsgen ENABLED 2097152 - ACTIVE - - pl v1-01 v1 ENABLED 2097152 - ACTIVE - - sd ams_wms0_359-01 v1-01 ENABLED 2027264 0 - - - sd ams_wms0_360-01 v1-01 ENABLED 69888 2027264 - - - dc v1_dco v1 - - - - - - v v1_dcl gen ENABLED 67840 - ACTIVE - - pl v1_dcl-01 v1_dcl ENABLED 67840 - ACTIVE - - sd ams_wms0_360-02 v1_dcl-01 ENABLED 67840 0 - - -
