HP OpenVMS 8.x manual Specifying the Volume Label, Specifying the On-Disk Structure Level

* these patches at a future time by use of the PRODUCT UNDO PATCH command.

Do you want to continue? [YES]

If you answer YES (the default), the recovery data sets are deleted and the OpenVMS upgrade continues.

Deleting RECOVERY DATA SET 001 ...

If you answer NO, the recovery data sets are not deleted and the OpenVMS upgrade aborts.

Do you want to continue? [YES] NO %PCSIUI-I-USERABORT, operation terminated by user request

You chose to retain recovery data on the target system disk.

The OpenVMS upgrade cannot continue.

Please correct the situation that prevents you from deleting the recovery data and then retry the upgrade.

6.3.6 Specifying the Volume Label

After you specify the target disk and, if applicable, check for recovery data, the procedure informs you of the volume label currently assigned to the target disk you specified and asks whether you want to keep that label. As shown in the following example, if you choose not to keep the label, you are prompted for a new label. The OpenVMS operating system uses the volume label to identify and reference the disk. Make sure the label you use is unique; problems occur if the same label is used by different disk volumes.

DKB400: is now labeled I64SYS.

Do you want to keep this label? (Yes/No) [Yes] NO

Enter volume label for target system disk: [I64SYS] I640831H1

You can accept the default label assigned by the system or specify a different volume label. (The label name has a limit of 12 characters that can include A to Z, 0 to 9, the dollar sign ($), hyphen (-), and underscore(_) characters).

NOTE: OpenVMS requires that the volume labels for all disks on your system or OpenVMS Cluster have unique labels. If a disk that has the same label as the system disk is mounted, various OpenVMS components will not function as intended or a node might crash during boot.

If you change the volume label for a disk in an OpenVMS Cluster, be sure to change the command that mounts the disk on other nodes in the cluster; otherwise, the disk will not mount on those nodes once they are rebooted.

6.3.7 Specifying the On-Disk Structure Level

If the target disk is currently initialized with On-Disk Structure Level 2 (ODS-2), the procedure informs you and gives you the option to convert the disk to On-Disk Structure Level 5 (ODS-5), as in the following example. If the target disk is currently initialized with ODS-5, the upgrade continues without displaying information about the disk structure. You are not asked whether to convert the system disk's structure or whether to enable hard links.

NOTE: If your disk was initialized with ODS-5, and hard links was not enabled but now you want to enable hard links, you can enable them prior to the upgrade by using the following commands as shown:

$ SET VOLUME/VOLUME_CHARACTERISTICS=HARD_LINKS SYS$SYSDEVICE

$ ANALYZE DISK_STRUCTURE/REPAIR SYS$SYSDEVICE

The target system disk is currently at On-Disk Structure Level 2 (ODS-2). It can be converted to On-Disk Structure Level 5 (ODS-5).
