Dynamic Root Disk: Downloads and Updates

Only if you are using VxVM roots: Verify (and if necessary download and install) the required patches for DRD on systems with VxVM roots:   (If you are not using VxVM roots, you can skip this step and continue with step 2.)

The table below indicates required patches when using DRD on HP-UX 11i v2 or 11i v3 on a system with VxVM roots utilizing VxVM 4.1. or 5.0.

To determine if you have a patch installed, execute the following command.   This example looks for the PHKL_37839 patch, which is required when running VxVM 4.1 on HP-UX 11i v2.

# /usr/sbin/swlist -l patch -a supersedes | \
/usr/bin/grep PHKL_37839

If PHKL_37839 or a superseding patch is not displayed in the output of the above command, then you need to install the PHKL_37839 patch.

Downloading PHKL_37839

To download PHKL_37839 and any dependencies, go to the HP IT Resource center (ITRC):
http://www.itrc.hp.com/service/patch/patchDetail.do?patchid=PHKL_37839

The above URL allows you to download the PHKL_37839 patch and the most current set of dependencies associated with it.   Note that after PHKL_37839 is selected for download, all dependencies will automatically be selected as well.   All patches will be downloaded at once, and can then be installed on a system.

Downloading PHKL_38188

To download PHKL_38188 and any dependencies, go to the HP IT Resource center (ITRC):
http://www.itrc.hp.com/service/patch/patchDetail.do?patchid=PHKL_38188

The above URL allows you to download the PHKL_38188 patch and the most current set of dependencies associated with it.   Note that after PHKL_38188 is selected for download, all dependencies will automatically be selected as well.  All patches will be downloaded at once, and can then be installed on a system.   The installation of PHKL_38188 requires a reboot.

Download the DRD software and dependencies:

You can download the DRD software free from the Web.   This download allows you to quickly and easily receive the latest DRD updates and defect fixes.   To get your free download, go to the DRD Software Depot download page:
http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=DynRootDisk

Install the DRD software and dependencies:

You can install DRD from a depot with the swinstall command.   For example, to install the bundle DynRootDisk from the /var/tmp/DRD_xxxxx depot location, execute the following command:

For HP-UX 11i v3 (11.31):
# /usr/sbin/swinstall -s /var/tmp/DRD_xxxxx.depot  \
DynRootDisk SD

For HP-UX 11i v2 (11.23):
# /usr/sbin/swinstall -s /var/tmp/DRD_xxxxx.depot  \
DynRootDisk

(Where DRD_xxxxx.depot is the location of the depot from which you are installing the DRD software.)

Note: If you are installing DRD from the HP-UX Operating Environment (OE) media and have version C or a prior version of the USB-00 product, you will get a warning as a result of the automatic selection and installation of PHKL_37815, which is meant to patch version D. For more information on this, please see the Update to USB Driver Support on HPUX 11iv3 document, which is under the USB-00 product on http://docs.hp.com. If you do not want to get patches that apply to the products installed with DynRootDisk, use the
-x autoselect_patches=false option.

Update the drd_unsafe_patch_list file (if necessary):

The /etc/opt/drd/drd_unsafe_patch_list file is delivered as a volatile file with the DRD product.   Most new patches are DRD-Safe; that is, they can be installed by the drd runcmd command to an inactive image without affecting the booted system.   However, some patches, such as those that deliver firmware updates, cannot be made DRD-Safe.

NOTE: The drd_unsafe_patch_list file is only updated when the list of patches that should not be managed by drd runcmd changes.

Follow this procedure to check the version of the drd_unsafe_patch_list file and update the file if it is out of date:
a. View the file at ftp://ftp.itrc.hp.com/export/DRD/drd_unsafe_patch_list.   (You can open this URL in a Web browser.)   Determine the "last updated" date listed in the file and make a note of it.

b. On your active system image, view the "last updated" date listed in the /etc/opt/drd/drd_unsafe_patch_list file and make a note of it.

c. Compare the dates from Step a and Step b and if the "last updated" date listed in the Step a file is later than the date listed in the Step b file, then your installed drd_unsafe_patch_list file is out of date and you need to continue to Step d (in this procedure) to update the file.   (If the "last updated" date listed in the Step a file is not later than the Step b file, then you do not need to update the drd_unsafe_patch_list file and you are finished with this procedure.)

d. If your installed drd_unsafe_patch_list file is out of date and needs to be updated (to handle potential new DRD-Unsafe patches), go to the HP IT Resource Center FTP site (see Step i below) to download the most recent drd_unsafe_patch_list file.   This file is updated when any new patch is determined to be inappropriate for use with the drd runcmd command.

Update the unsafe patch list as follows:
i) Download the ftp://ftp.itrc.hp.com/export/DRD/drd_unsafe_patch_list file to /etc/opt/drd/drd_unsafe_patch_list on your active system image.
If you have not created a clone, then you are done with updating the drd_unsafe_patch_list file and have finished this procedure.   If you have created a clone, continue with Step ii.

ii) Because DRD uses the copy of the drd_unsafe_patch_list file on the inactive system image, the copy on that image must also be updated.   If there is a clone, mount the inactive system image:
# /opt/drd/bin/drd mount

iii) If there is a clone, copy the drd_unsafe_patch_list file to the inactive system image:
# /usr/bin/cp /etc/opt/drd/drd_unsafe_patch_list \
/var/opt/drd/mnts/sysimage_00*/etc/opt/drd/drd_unsafe_patch_list

NOTE: If you download the file to a Windows system and then copy it to an HP-UX system, DOS-type carriage-return line feeds might be inserted in the file.   To eliminate these characters, use the dos2ux command.

If you plan to use the new drd rehost command on HP-UX 11i v3 (11.31), you need to install PHCO_36525, which includes changes to /sbin/auto_parms, and PHCO_39064, which provides the new sysinfo(4) manpage from the depot you downloaded in Step 2.

Execute the following command to install PHCO_36525 and PHCO_39064:
# /usr/sbin/swinstall -s /var/tmp/DRD_xxxxx.depot  \
PHCO_36525   PHCO_39064

(Where DRD_xxxxx.depot is the location of the DRD depot from which you are installing the patches.)
