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

>

1-2Check the status of volume paths connected to each Fibre Channel card using the controller numbers that were checked in Step 1-1.

In this step, check the controller number corresponding to the volume for which "DISABLED" is displayed.

# vxdmpadm getsubpaths ctlr=c<controller number>

Example (for ETERNUS DX410)

# vxdmpadm getsubpaths ctlr=c6

NAME STATE PATH-TYPE DMPNODENAME ENCLR-TYPE ENCLR-NAME

=========================================================================

sdb	ENABLED	-	sdb	FJ_DX400	fj_dx400
sdc	ENABLED	-	sdc	FJ_DX400	fj_dx400
sdd	ENABLED	-	sdd	FJ_DX400	fj_dx400
# vxdmpadm getsubpaths ctlr=c7
NAME	STATE	PATH-TYPE	DMPNODENAME	ENCLR-TYPE	ENCLR-NAME

=========================================================================

sde	DISABLED	-	sdb	FJ_DX400	fj_dx400
sdf	ENABLED	-	sdc	FJ_DX400	fj_dx400
sdg	ENABLED	-	sdd	FJ_DX400	fj_dx400

In this example, "DISABLED" is displayed for the "sde" volume.

The controller number of the Fibre Channel card in which the volume cannot be recog- nized is "c7".
