Re: Accessing a business copy lun


which disksubsystem you used for business copy? Which tool?

Do you want to access the BC-devices on another host?

Re: Accessing a business copy lun

here is how I do it.
1. Present the Business copy LUN to the other server
2. On the server scan the Business copy LUN in
#ioscan -fnC disk

3.Create all teh device files for the newly scanned LUN
#insf -e
Now the new LUN should be seen by
#ioscan -funC disk

4.On the original server export the volumegroup with the map file creation
#/usr/sbin/vgexport -p -v -s -m vg_name

ftp the map file over to the Business copy server

5. Now go ahead and create the directory on the Business copy server
#mkdir /dev/vg_name
6. Create the group file under this directory
mknod group c 64 Minornumber

7. Import the volumegroup in
#/usr/sbin/vgimport -v -s -m /dev/vg_name

8. create the mount point
#mkdir /mountpoint

9. Activate the volumegroup

#vgchange -a y /dev/vg_name

10. Mount the filesystems

That is it. If you need more help on any of these please let me know

...Also, Please have the Business copy in a split state after syncing to the primary,when mounting on the second server.
