Hello,
using Linux native multipathing (DM) I can name each device in config files and then refer to that names.
Is it possible to do the same using HDLM ? I need a consistent naming across servers and want
the same LDEV be named i.e. sddlma on all servers working in cluster.
How to do that using HDLM ?
Hi,
Persistent naming was introduced in HDLM v7.5. Here's the basic summary of the procedure:
1) Create a definition file: /opt/DynamicLinkManager/bin/dlmchname -o
2) The file will be at /etc/opt/DynamicLinkManager/dlmchname.conf. The content is similar to this:
3585011299 0090 sddlmac
3585011299 0091 sddlmab
3585011299 0092 sddlmaa
The columns are serial number, LDEV ID, and HDLM device name.
3) Modify the HDLM device names to whatever you want
4) Update HDLM using definition file: /opt/DynamicLinkManager/bin/dlmchname -f
5) Reset the server
6) Copy the definition file to other servers in the cluster and run steps 4 & 5.
