Many DMP paths are disable

[Unix_Support1]

Hi,

I am facing issue with DMP paths. There are 2 types of SAN sttached with the affected system, XP & EMC. No issue with XP. But EMC's one or more paths are disable.

[root@lme0020 tmp]# vxdmpadm getsubpaths all|grep -v ENABLED|wc -l
164
[root@lme0020 tmp]# vxdmpadm getsubpaths all|grep -v ENABLED|head -3

Also there is no enclosure info for EMC in "vxdmpadm listenclosure all" output. In the previous out put you can find enclosure "emc_clariion0" ,which is not visible in following out put.

Which Storage Foundation version?

Depending on the version, you might need to download the ASL separately.

[Unix_Support1]

Hi,

SF version is as give as below.

VRTSvxvm-common-5.0.40.00-MP4_RHEL5
VRTSvxvm-platform-5.0.40.00-MP4_RHEL5
 

Do i really need to install ASL? becuase EMC is connected with many servers but the issue is specific to this system

Regards,

The newer VxVM versions normally include all ASL/APM's.

Please verify:

vxdmpadm listapm
vxddladm listsupport

[Unix_Support1]

Please refer the below output.

OK - so the APM/ASL's are definately installed:

dmpCLARiiON.ko     dmpCLARiiON            1        CLR-A/P           Active
dmpCLARiiON.ko     dmpCLARiiON            1        CLR-A/PF          Active

libvxCLARiiON.so    DGC                 All

Next thing to check is array setting as per the Hardware TechNote:
