HP StorageWorks P9000 Data Exchange User Guide (T1620-96016, September 2010)

• Volume labels. A Data Exchange volume with a volume label cannot be shared between
open-system platforms that use volume labels. Table 33 on page 58 shows the allowable
configurations for sharing Data Exchange volumes between open-system platforms for the
storage systems. Table 34 on page 59 shows the allowable configurations for sharing Data
Exchange volumes between open-system platforms for the storage systems. HP-UX and IBM
AIX do not use volume labels, so Data Exchange volumes can always be shared with these
platforms. Labels are optional for DIGITAL UNIX/Tru64 and Windows, so Data Exchange
volumes can be shared with these platforms only if they have no label. Solaris always writes
volume labels, so Data Exchange volumes can never be shared between these two platforms,
but can be shared with the other platforms (HP, IBM, Tru64, Windows) as long as they do
not have labels.
NOTE:
Solaris may display the following warning messages when formatting and labeling a Data
Exchange volume. This is normal, and the user can ignore these messages.
Warning: error writing VTOC
Warning: no backup labels
Write label failed
Access to shared volumes is given only to “root.”
3. For UNIX hosts, make sure to set up the desired access privileges for each Data Exchange volume
(for example, using groups and/or chmod command). See the OS user documentation for
information on access permission rights. For Windows, Administrator access is required to access
the Data Exchange volumes.
4. On the mainframe host, make sure to initialize and write the VTOC for each FXmto and FXotm
volume to enable the mainframe host to access the volumes. The ICKDSF media maintenance
utility can be used to perform these tasks.
5. After Data Exchange software installation, make sure to format each FXoto volume using the FMT
utility on the UNIX/Windows host. This enables the FXoto intermediate datasets to be allocated.
