8 Troubleshooting DRD

This chapter provides information about unexpected DRD situations and outcomes.

For the most recent troubleshooting information, check the DRD Frequently Asked Questions

document at http://www.hp.com/go/drd-docs.

8.8.1.1 Q: Why can't I see the inactive system image file systems when I run the bdf command?

A: You have to mount the inactive system image before you can see the file systems

using bdf. Use the drd mount command to mount the inactive system image.

8.8.1.2 Q: I can't remember which disk was used as the target of my clone operation. How

can I identify it?

A: Use the drd status command.

8.8.1.3 Q: I issued a drd activate command but changed my mind and do not want to

boot the clone. How can I undo the drd activate command?

A: If you run drd activate and then decide not to boot the inactive image on the

next reboot, use the drd deactivate command to set the primary boot disk to the

currently booted disk. For further information on the drd deactivate command, see

The drd deactivate command and the drd-deactivate(1M) manpage.

8.8.1.4 Q: Can I change file system sizes when I create a clone?

A: This release of DRD does not provide a mechanism for resizing file systems during

a drd clone operation. However, after the clone is created, you can manually change

file system sizes on the inactive system without needing an immediate reboot. For

information on resizing file systems, see the Dynamic Root Disk: Quick Start & Best

Practices white paper, available at http://www.hp.com/go/drd-docs.

8.8.1.5 Q: What versions of LVM are supported by DRD?

A: DRD supports the following LVM root volume group versions:

• DRD A.3.5.* and earlier:

HP-UX 11i v2: LVM 1.0◦

◦ HP-UX 11i v3: LVM 1.0

• DRD A.3.6.* and later:

◦ HP-UX 11i v2: LVM 1.0

◦ HP-UX 11i v3: LVM 1.0 and LVM 2.2

8.8.1.6 Q: What versions of VxVM are supported by DRD?

A: DRD supports VxVM versions 4.1, 5.0, 5.0.1 and 5.1SP1. Versions of DRD prior

to A.3.13 support VxVM versions up to 5.1SP1 with disk group version (DGV) up to

140. Only A.3.13 and higher versions of DRD support 5.1SP1 VxVM with DGV 160.

Staring with March 2014 release of HP-UX 11i v3, a VxVM root disk group with 5.1SP1

VxVM is configured with DGV 160 by default during cold installation using Ignite-UX.

To check the DGV of the root disk group, run:

/usr/sbin/vxdg list rootdg | grep version.
