How to check Multipath in veritas

Diposkan oleh ndevtuna di 7:12 PM Label:
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

Can you tell me how to check "PATHS =4". On our server, using the command "vxdmpadm listctlr all" have the output below :
root@U2NH01 # vxdmpadm listctlr all
CTLR-NAME ENCLR-TYPE STATE ENCLR-NAME
=====================================================
c0 Disk ENABLED disk
c2 HUAWEI-S2600- ENABLED huawei-s2600-0
c4 HUAWEI-S2600- ENABLED huawei-s2600-0

Hi Jack,
you can run the command :
# vxdmpadm getdmpnode enclosure=huawei-s2600-0

Hi Krusty,

From data provided, you use data from sun storedge 3510 and i see your path still single path.
