too, to validate selections and help make the change to the agile naming model.
Support for >2 TB boot disk
Starting with the HP-UX 11i v3 OE Update March 2013 release, the maximum size of the boot
disk has been increased from 2 TB to 16 TB on HP Integrity systems. (HP 9000 systems have
supported the boot disk or root volume group up to the 2 TB maximum size since the initial HP-UX
11i v3 OE February 2007 release.)
The >2 TB boot disk support is available with Logical Volume Manager (LVM) layout and currently
not available on VxVM and Whole Disk layouts. To configure >2 TB disk as boot disk, you have
to navigate to Basic tab -> Filesystem -> select Logical Volume Manager (LVM) with VxFS from the
itool interface.
Update the Ignite-UX software on the Ignite-UX servers with the Ignite-UX bits.
NOTE: The Ignite-UX software is delivered with the HP-UX 11i v3 OE Update March 2013
release or higher for configuring the boot disk >2 TB in size.
NOTE: Support for >2 TB boot disk support is available with HP-UX 11i v3 OE Update March
2013 release or higher to HP Integrity systems, and this feature is not available and supported on
the HP-UX versions earlier than OE Update March 2013 release.
During the cold installation, the default LVM Volume Group Version set by Ignite-UX is 1.0. This
limits the size of the boot size to 2 TB, and the remaining space on the disk will be unused. To
utilize the full disk capacity beyond 2 TB (and up to 16 TB max) for boot disk with LVM, you have
to update the LVM’s Volume Group Version to 2.2 or later versions. You can do this by navigating
to Filesystem tab > Advanced Tasks > Group parameters tab > LVM Version in the Ignite-UX itool
user interface. For more information, see LVM Volume Group Version 2.2 at: http://www.hp.com/
go/hpux-core-docs
The VxFS File System size chosen for configuring any volume is limited to 2 TB during the installation
and any size configured beyond 2 TB will be capped to a maximum of 2 TB . You can manually
extend the size of the VxFS File System to >2 TB, post installation, if Online JFS License product is
installed on the system.
