Initializing disks

Install the driver and HBA card. Refer to the documentation from the vendor for instructions.

After you physically add shared disks to the nodes, you must initialize them as VxVM disks and verify that all the nodes see the same disk. Use the example procedure; see the Veritas Volume Manager Administrator's Guide for more information on adding and configuring disks.

 To initialize disks

1. Make the new disks recognizable. On each node, enter:

   # ioscan -nfC disk

   # insf -e

   Warning: The HP-UX man page for the insf command instructs you to run the command in single-user mode only. Running insf -e in multi-user mode is acceptable assuming no other user is accessing any of the device files. This command can change the mode, owner, or group of an existing special (device) file, or unlink and recreate a file. Special files that are currently open may be left in an indeterminate state.
   
2. If the ASL for the array you are adding is not installed, obtain and install it on each node before proceeding. The ASL for the supported storage device you are adding is available from the disk array vendor or Veritas technical support.
3. Verify that the Array Support Library (ASL) for the disk array is installed on each of the nodes. Run the following command on each node and examine the output to verify the installation of ASL:

   # vxddladm listsupport all

   LIB_NAME ARRAY_TYPE VID PID

   ==============================================================

   .

   libvxemc.sl A/A EMC SYMMETRIX

   .

4. Scan all disk drives and their attributes, update the VxVM device list, and reconfigure DMP with the new devices. Type:

   # vxdisk scandisks

   See the Veritas Volume Manager documentation for details on adding and configuring disks.

5. To initialize the disks as VxVM disks, use one of the following methods:
   • Use the interactive vxdiskadm utility to initialize the disks as VxVM disks.

     For more information see the Veritas Volume Managers Administrator's Guide.

   • Use the vxdisksetup command to initialize a disk as a VxVM disk.

     vxdisksetup -i device_name format=cdsdisk

     The example specifies the CDS format:

     # vxdisksetup -i c2t13d0 format=cdsdisk
