Listing supported disks in the DISKS category

To list disks that are supported in the DISKS (JBOD) category, use the following command:

#vxddladm listjbod

Adding unsupported disk arrays to the DISKS category

Disk arrays should be added as JBOD devices if no ASL is available for the array.

JBODs are assumed to be Active/Active (A/A) unless otherwise specified. If a suitable ASL is not available, an A/A-A, A/P or A/PF array must be claimed as an Active/Passive (A/P) JBOD to prevent path delays and I/O failures.

Caution: The procedure in this section ensures that Dynamic Multipathing (DMP) is set up correctly on an array that is not supported by Veritas Volume Manager. If the native multipathing in HP-UX 11i v3 does not recognize such an array as being multipathed, Veritas Volume Manager treats the independent legacy paths to the disks as separate devices, which can result in data corruption.

To add an unsupported disk array

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

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

where device_name is the device name of one of the disks in the array (for example, /dev/rdsk/c1t20d0). 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 is sample output:

#/etc/vx/diag.d/vxdmpinq /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.

2Stop all applications, such as databases, from accessing VxVM volumes that are configured on the array, and unmount all VxFS file systems and checkpoints that are configured on the array.

3If the array is of type A/A-A, A/P or A/PF, configure it in autotrespass mode.

4Enter the following command to add a new JBOD category:

# vxddladm addjbod vid=vendorid pid=productid \
