To add an unsupported disk array to the DISKS category

1. Use the following command to identify the vendor ID and product ID of the disks in the array:

   # /etc/vx/diag.d/vxscsiinq device_name

   where device_name is the device name of one of the disks in the array. Note the values of the vendor ID (VID) and product ID (PID) in the output from this command. For Fujitsu disks, also note the number of characters in the serial number that is displayed.

   The following example shows the output for the example disk with the device name /dev/rdsk/c1t20d0

   # /etc/vx/diag.d/vxscsiinq /dev/rdsk/c1t20d0

   Vendor id (VID)     : SEAGATE
   Product id (PID)    : ST318404LSUN18G
   Revision            : 8507
   Serial Number       : 0025T0LA3H

   In this example, the vendor ID is SEAGATE and the product ID is ST318404LSUN18G.

2. Stop all applications, such as databases, from accessing VxVM volumes that are configured on the array, and unmount all file systems and Storage Checkpoints that are configured on the array.
3. If the array is of type A/A-A, A/P or A/PF, configure it in autotrespass mode.
4. Enter the following command to add a new JBOD category:

   # vxddladm addjbod vid=vendorid [pid=productid] \
   [serialnum=opcode/pagecode/offset/length]
   [cabinetnum=opcode/pagecode/offset/length] policy={aa|ap}]

   where vendorid and productid are the VID and PID values that you found from the previous step. For example, vendorid might be FUJITSU, IBM, or SEAGATE. For Fujitsu devices, you must also specify the number of characters in the serial number as the argument to the length argument (for example, 10). If the array is of type A/A-A, A/P or A/PF, you must also specify the policy=ap attribute.

   Continuing the previous example, the command to define an array of disks of this type as a JBOD would be:

   # vxddladm addjbod vid=SEAGATE pid=ST318404LSUN18G

5. Use the vxdctl enable command to bring the array under VxVM control.

   # vxdctl enable

6. To verify that the array is now supported, enter the following command:

   # vxddladm listjbod

   The following is sample output from this command for the example array:

   VID     PID          SerialNum            CabinetNum   Policy
                    (Cmd/PageCode/off/len) (Cmd/PageCode/off/len)
   ==============================================================
   SEAGATE ALL PIDs  18/-1/36/12           18/-1/10/11    Disk
   SUN     SESS01   	18/-1/36/12   	       18/-1/12/11 		 Disk

7. To verify that the array is recognized, use the vxdmpadm listenclosure command as shown in the following sample output for the example array:

   # vxdmpadm listenclosure
   ENCLR_NAME ENCLR_TYPE ENCLR_SNO STATUS    ARRAY_TYPE LUN_COUNT
   ==============================================================
   Disk       Disk       DISKS     CONNECTED Disk       2

   The enclosure name and type for the array are both shown as being set to Disk. You can use the vxdisk list command to display the disks in the array:

   # vxdisk list
   DEVICE   TYPE       DISK     GROUP      STATUS
   Disk_0   auto:none  -        -          online invalid
   Disk_1   auto:none  -        -          online invalid
   ...

8. To verify that the DMP paths are recognized, use the vxdmpadm getdmpnode command as shown in the following sample output for the example array:

   # vxdmpadm getdmpnode enclosure=Disk
   NAME   STATE   ENCLR-TYPE PATHS ENBL DSBL ENCLR-NAME
   =====================================================
   Disk_0 ENABLED Disk       2     2    0    Disk
   Disk_1 ENABLED Disk       2     2    0    Disk
   ...

   This shows that there are two paths to the disks in the array.

   For more information, enter the command vxddladm help addjbod.
