Converting a powervxvm disk to auto:simple

In VxVM 4.0, and particularly in previous releases, EMCpower disks can be defined by a persistent disk access record (darec) using powervxvm script, and identified as simple disks. If an EMCpower disk is used using powervxvm, it must be manually converted to auto:simple format before you upgrade to VxVM 7.4.1.

If there are any controllers or devices that are suppressed from VxVM as powervxvm requirement, then such controllers or disks must be unsuppressed. This is required for Veritas DMP to determine the association between PowerPath metanodes and their subpaths. After the conversion to auto:simple is complete, the powervxvm script is no longer useful, and should be disabled from startup script.

The following example is used to illustrate the procedure. The ls command shows the mapping of the EMC disks to persistent disk access records:

# ls -l /dev/vx/rdmp/
crw-------   1 root     root     260, 76 Feb  7 02:36 emcpower0c

# vxdisk list
DEVICE       TYPE            DISK         GROUP        STATUS
c6t0d12s2    auto:sliced       -            -          online
emcpower0c   simple          ppdsk01      ppdg         online

# vxprint
Disk group: fdg
TY NAME     ASSOC      KSTATE  LENGTH   PLOFFS STATE TUTIL0 PUTIL0
dg ppdg     ppdg       -       -        -      -     -      -
dm ppdsk01  emcpower0c -       2094960  -      -     -      -

To convert an EMCpower disk (defined using powervxvm) to auto:simple format

Stop all the volumes in the disk group, and then deport it:
```
# vxvol -g ppdg stopall
# vxdg deport ppdg
```

Use the vxdisk rm command to remove all emcpower disks from VxVM:

# vxdisk rm emcpower0c

If you now run the vxdisk list command, the EMCpower disk is no longer displayed:

# vxdisk list
DEVICE       TYPE            DISK         GROUP        STATUS
c6t0d12s2    auto:sliced       -            -          online

Use the vxprtvtoc command to retrieve the partition table entry for this device:
```
# /etc/vx/bin/vxprtvtoc -f /tmp/vtoc /dev/vx/rdmp/emcpower0c
```

Use the vxedvtoc command to modify the partition tag and update the VTOC:

# /etc/vx/bin/vxedvtoc -f /tmp/vtoc /dev/vx/rdmp/emcpower0c 
# THE ORIGINAL PARTITIONING IS AS FOLLOWS:
# SLICE     TAG  FLAGS   START  SIZE
  0         0x0  0x201   0      0
  1         0x0  0x200   0      0
  2         0x5  0x201   0      17675520

# THE NEW PARTITIONING WILL BE AS FOLLOWS:
# SLICE     TAG  FLAGS   START  SIZE
  0         0xf  0x201   0      17675520
  1         0x0  0x200   0      0
  2         0x5  0x201   0      17675520

DO YOU WANT TO WRITE THIS TO THE DISK ? [Y/N] :Y 
WRITING THE NEW VTOC TO THE DISK #

Upgrade to VxVM 7.4.1 using the appropriate upgrade procedure.

After upgrading VxVM, use the vxdisk list command to validate the conversion to auto:simple format:

# vxdisk list
DEVICE       TYPE            DISK         GROUP        STATUS
c6t0d12s2    auto:sliced       -            -          online
emcpower0s2  auto:simple       -            -          online

Import the disk group and start the volumes.

# vxdg import ppdg
# vxvol -g ppdg startall
# vxdisk list

DEVICE       TYPE            DISK         GROUP        STATUS
c6t0d12s2    auto:sliced       -            -          online
emcpower0s2  auto:simple     ppdsk01       ppdg        online
