HP EVA-to-3PAR Online Import Migration Guide (T5494-96577)

IMPORTANT: Once a migration begins, it cannot be stopped.
15. When all the conditions have been met, click Start Data Transfer.
A progress bar indicates how much of the data has been migrated. The progress bar is
refreshed every 15 seconds.
16. Zone the host to the 3PAR destination storage system, establishing the data paths between
the host and the destination.
17. 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 automatically identify the remaining set of disks
that were mapped to the given volume group.
The following example 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 AIX1VGvolume 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.
The following example 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 12a.
