Administering Dynamic Multipathing (DMP)
Disabling and Enabling Multipathing for Specific Devices
Chapter 3 119
• Select option 7 to enable multipathing for disks that match a
specified Vendor ID and Product ID.
NOTE This option requires a reboot of the system.
Make VID:PID visible to DMP
Menu: VolumeManager/Disk/IncludeDevices/VIDPID-DMP
Use this operation to make vxdmp multipath disks returning a specified
VendorID:ProductID combination again.
As a result of this operation, all disks that return VID:PID matching the
specified combination will be multipathed by vxdmp again.
You can specify a VID:PID combination at the prompt. The specification can be as
follows:
VID:PID where VID stands for Vendor ID
PID stands for Product ID
(The command vxdmpinq in /etc/vx/diag.d can be used to obtain the Vendor ID and
Product ID)
Both VID and PID can have an optional ’*’ (asterisk) following them.
If a ’*’ follows VID, it will result in the inclusion of all disks returning
Vendor ID starting with the specified VID. The same is true for Product ID as
well. Both VID and PID should be non NULL. The maximum allowed lengths for Vendor
ID and Product ID are 8 and 16 characters respectively.
Some examples of VID:PID specification are:
all - Exclude all disks
aaa:123 - Exclude all disks having VID ‘aaa’ and PID ‘123’
aaa*:123 - Exclude all disks having VID starting with ‘aaa’and PID ‘123’
aaa:123* - Exclude all disks having VID ‘aaa’ and PID starting with ‘123’
aaa:* - Exclude all disks having VID ‘aaa’ and any PID
Enter a VID:PID combination:[<pattern>,all,list-exclude,q,?]
