HP 3PAR Online Import for EMC Storage Data Migration Guide

Initiating a createmigration command to create a host on a destination
produces an error message

-NA- preparationfailed(-NA-)(OIUERRPREP1014:Error creating host on destination;)
Solution: This problem can occur when the host is already added to the destination. Delete the
host from the destination and then execute the createmigration command.
HP Storage Migration group user receives an error message when attempting
to login to the Online Import Utility
Example 35 OIU login error
CLI Version: 1.1.0
Enter IPADDRESS: 10.64.0.101
Enter USERNAME: tester
Enter PASSWORD:
>ERROR: Invalid credentials, Please try with valid credentials
Enter IPADDRESS:
Solution: When the user in the “User” group was created the checkbox for “User must change
password at next logon” was checked by default. After unchecking the checkbox, login succeeds.
Migrated LUNs with no host in a Storage Group failed OIU:createmigration
Solution: If migrated LUNs do not have an associated host, the migration type must be offline.
OIU:createmigration error for LUN name or host name containing special
characters
Solution: HP 3PAR Online Import Utility for EMC Storage does not support special characters in
the LUN name or host name and will cause an error on the createmigration command if
special characters are present in the names. Recommend changing the unsupported LUN and/or
host name to continue migration.
HP 3PAR Online Import Utility for EMC Storage does not open on Windows
7 when double-clicking icon or right mouse-click icon and selecting “Run As
Administrator”
Workaround: Run a Command Prompt window and perform the following steps:
1. Change directory to the location where HP 3PAR Online Import Utility for EMC Storage was
installed (default location is C:\Program Files (x86)\Hewlett-Packard\hp3paremcoiu)
2. Change directory to the CLI sub-folder.
3. Run the OIUCLI.bat to start the utility.
OIU:startmigration error for Host name greater than 31 characters or with
spaces
Problem: When migrating a host with a long name or name with spaces, OIU truncates the host
name to 31 characters or replaces spaces with underscores in order to complete the
createmigration command. However, startmigration will fail with Unable to unpresent
a source volume to source host error.
