Disabling and Enabling Multipathing for Specific Devices

❖ Select option 2 to make speciﬁed paths visible to VxVM.

Re-include paths in VxVM

Menu: VolumeManager/Disk/IncludeDevices/PATH-VXVM

Use this operation to make one or more paths visible to VxVM again.

As a result of this operation,the specified paths will become

visible to VxVM again.

You can specify a pathname or a pattern at the prompt. Here are

some path selection examples:

all: all paths

c3t4d2: a single path

list: list all paths on the system

Enter a pathname or pattern :[<pattern>,all,list,list-exclude,q,?]

❖ Select option 3 to make disks visible to VxVM that match a speciﬁed Vendor ID and

Product ID.

Make VID:PID visible to VxVM

Menu: VolumeManager/Disk/IncludeDevices/VIDPID-VXVM

Use this operation to make all disks returning a specified

VendorID:ProductID combination visible to VxVM again.

As a result of this operation, disks that return VendorID:ProductID

matching the specified combination will be made visible to VxVM

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 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.
