As a result of this operation, all disks that return VID:PID matching the sp
ecified combination will be multipathed by vxdmp again.
VxVM INFO V-5-2-1407 You can specify a VID:PID combination at the prompt. Th
e 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 fo
r 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,?]
