HP EVA-to-3PAR Online Import Migration Guide

18. Perform the following steps on the AIX host:
a. Rescan 3PAR disks using the cfgmr command.
b. Use the mapping information obtained while performing the steps on the AIX host and
import the volume groups using the importvg –y vgname pvname command, where
pvname corresponds to the 3PAR disk whose PVID is mapped to vgname.
c. After the mapping information, if a volume group is mapped to multiple disks, specify a
disk from the list of disks. The importvg command automatically identify the remaining
set of disks that were mapped to the given volume group.
Example 1 (page 23) illustrates this mapping:
Example 1 VG to PVID mapping before removing the EVA disks from the system
#lspv
hdisk0 00f825bdd5f7e96e rootvg active
hdisk1 00f825bd4a05917b None
hdisk2 00f825bd5dfc80c6 AIX1VG active
hdisk3 00f825bd5dfc82c1 AIX2VG active
Note that the AIX1VG volume group is mapped to the disk with PVID
00f825bd5dfc80c6, and AIX2VG is mapped to the disk with PVID
00f825bd5dfc82c1. While the disks are re-scanned after zoning in the host and 3PAR
destination array, the lspv command will be as follows:
# lspv
hdisk0 00f825bdd5f7e96e rootvg active
hdisk1 00f825bd4a05917b None
hdisk7 00f825bd5dfc80c6 None
hdisk8 00f825bd5dfc82c1 None
d. Import the VGs by specifying the corresponding disks with the same PVIDs.
Example 2 (page 23) illustrates how to import VGs through destination paths.
Example 2 Importing the VGs through the destination paths
# importvg -y AIX1VG hdisk7
AIX1VG
# importvg -y AIX2VG hdisk8
AIX2VG
# lspv
hdisk0 00f825bdd5f7e96e rootvg active
hdisk1 00f825bd4a05917b None
hdisk7 00f825bd5dfc80c6 AIX1VG active
hdisk8 00f825bd5dfc82c1 AIX2VG active
e. If the applications use EVA disks in raw format, re-configure them to point to the
corresponding 3PAR disk having the same PVID.
f. Restart the applications that were stopped in Step 13.a.
Migrating an HP-UX host
Migration of HP-UX 11i V3
The HP-UX 11i V3 hosts can be migrated using the online data migration procedure. Both HP-UX
11i V3 standalone as well as Serviceguard cluster hosts can use online data migration.
1. In Command View, select the Storage Systems point of view.
2. Select the HP EVA to 3PAR StoreServ Online Import tab.
3. In the left navigation pane, select a host.
You can select a host folder, an individual host, or a user defined host folder.
