Appendix A Restoration Procedure for when a Path Degrades in a VERITAS Volume Manager Environment

If a path degrades when VERITAS Volume Manager is used, some volumes may not be recog- nized properly after path restoration.

In this case, volume recognition is required after restoring LUN recognition using the Change LUN State Utility provided by each Fibre Channel card vendor.

Procedure

1Check the Fibre Channel card's controller number and status.

Use the "vxdmpadm" command to check the controller number and controller status of the Fibre Channel card that corresponds to the unrecognized volume.

1-1Check the controller number of the Fibre Channel card in which there is a path connected to the ETERNUS DX Disk storage system.

# vxdmpadm listctlr all

Example (for ETERNUS DX410)

# vxdmpadm listctlr all

In this example, the controller numbers of the Fibre Channel cards connected to the

ETERNUS DX410 are "c6" and "c7".
