Hello All,

 

We are going to have one migration of our machine/server, details are given below.

 

Migration of storage LUNs(EMC to Hitachi)--almost 60 LUNs

OS is --HPUX11.23

Activity type-offline.

System is part of a two node cluster.HP service guard.

 

Now what are the exact steps & necessary precaution we need to take care.

Arup

Verify Zoning 

Check dual connectivity ( San -Switch end )

Reconfigure cluster lock disk on new Storage ................CRITICAL

Ensure Application & DB shutdown before migration .

How are you migrating , any tool ? We used openmigrator tool from EMC .
