recovering from ignite

[khilari]

• After we have taken the ignite image, when we are restoring, do the other vgs also get restored or do we have to use vgexport first and put them in the /tmp file so we can get them by running vgimport once the recovery is done, because while making a tape recovery we r only using –x inc_entire=vg00 and not including any other vg ?.

The vg information will be recovered not the data in the vgs unless you specifially told ignite to do so.

During recovery, if the same exact devices exist, you would be able to immediately execute a vgdisplay and see all previously configured vgs and lvols. If these devices are the same devices that previously had data on them and you did not delete the data then the data would also be intact ( but not actually recovered per say ) just the configs.

A different example would be an offsite recovery where you have new/different storage. The device files and HW paths are typically not the same, then you would need to map/import/rebuild your vgs, then your lvs, then mount your fs, and restore your data from tape.
