Installation guide
Connecting Violin Memory Arrays to IBM AIX and PowerVM
21 www.vmem.com
If the Array is not recognized as a VMEM enclosure this means that the Array Support library for Violin Storage
is not installed on the server. This can be verified by running the below command. If this command returns null,
then please check if ASL update package is installed for Violin Arrays and contact Symantec Support if
required.
One can verify multi-pathing at a DMP level by picking a LUN as discovered by DMP and listing the sub-paths
of a DMP node.
We pick the LUN vmem0_a1d78869 and seek its DMP subpaths.
8.4.5 Correlating LUNS in DMP Command-line vs. Violin Array Management GUI
The steps listed below provide an easy way to correlate LUNS from DMP Command-line v/s Array
Management GUI:
In the Violin GUI, the suffix of a LUN Sr no can be
correlated with the Array Volume ID(AVID) as
discovered by DMP
The suffix of the Sr. no of Exported LUNs will show as
the suffix of a Disk access (DA) name in DMP
Command-line.
e.g. #vxdisk list | grep -i < suffix of sr no >
# vxddladm listsupport | grep -i violin
libvxviolin.so VIOLIN SAN ARRAY
bash-4.2# vxdisk list ( partial listing)
