5 komentar
1. Check What is Enclosure name from storage in server

root# vxdmpadm listctlr all
CTLR-NAME ENCLR-TYPE STATE ENCLR-NAME
=====================================================
c1 Disk ENABLED Disk
c0 Disk ENABLED Disk
c5 TagmaStore-USP ENABLED TagmaStore-USP1
c2 TagmaStore-USP ENABLED TagmaStore-USP1
c5 TagmaStore-USP ENABLED TagmaStore-USP0
c2 TagmaStore-USP ENABLED TagmaStore-USP0

2. Check multipath a disk, if PATHS =4 that indicates a disk already multipath, if PATHS = 2 that is single path.


root# vxdmpadm getdmpnode enclosure=TagmaStore-USP0
NAME STATE ENCLR-TYPE PATHS ENBL DSBL ENCLR-NAME
