How to mount 3PAR Virtual Copy onto RHEL Servers
By Dusan Baljevic (dusan.baljevic@ieee.org)
This was done as part of HP Edu labs as proof of concept that I prepared for 3PAR course. Testing
Virtual Copy export to RHEL 5.x server with LVM… The most crucial command was vgimportclone on
RHEL server…
A. On Linux server check the WWNs:
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)
# cat /sys/class/fc_host/host*/port_name
0x50014380167d7e94
0x50014380167d7e96
B. Go to 3PAR MC or CLI and create host definition for Linux server,
based on the WWNs above…
C. Then, within 3PAR MC or CLI export some VVs to Linux server. In
This case, two volumes were exported: one fully provisioned, and one
thin provisioned.
D. Go to Linux server and check the new disks:
# hp_rescan -a
Rescanning /sys/class/scsi_host/host0
Rescanning /sys/class/scsi_host/host1
# multipath -l
