HP StorageWorks XP Provisioning Manager User Guide (December 2005)

Viewing Host Information 105
• A path manager other than Dynamic Link Manager is also used
However for an LU managed by a path manager other than Dynamic Link Manager, Provisioning
Manager cannot acquire the information managed by the path manager, such as the number of paths and
data paths. In HP-UX, however, Provisioning Manager can acquire information about LUs managed by
PV-link.
To specify LU settings in the above environment, verify the following items:
• That the target LU is managed by Dynamic Link Manager
# When file systems or device files are added or expanded, Provisioning Manager assumes that all LUs to be
added are managed by Dynamic Link Manager.
About Logical Disk Manager
Provisioning Manager virtually creates a volume group that has the same name as the logical volume.
The corresponding volume group does not exist on the host.
About SDS/SVM
If the volume manager in use is SDS/SVM, Provisioning Manager can only view host information.
Only volumes created under the following conditions can be displayed:
• When the logical volume attribute is one of the following:
• Stripe/concatenated volume (stripe/concatenated metadevice)
• Mirror volume (mirror metadevice)
• RAID5 volume (RAID5 metadevice)
• Transaction (logging) volume (trans metadevice)
• Soft partition
However, the displayed information is limited on the logical volumes that satisfy one of the following
conditions:
• When a logical volume exists on another logical volume, only the top-level logical volume is
displayed. The lower logical volume information is not displayed.
• If the slice constituting one file system or device file is shared by another file system or device file, the
shared volume information is displayed only as one component among those file systems or device
files.
• If the slice constituting one file system or device file is shared by another file system or device file and
the whole shared-volume information is displayed as one component among those file systems or
device files, Provisioning Manager does not display other file systems or device files.
Provisioning Manager virtually creates a volume group that has the same name as the logical volume.
The corresponding volume group does not exist on the host.
The following figures illustrate the scope of displayed information when the logical volume is shared.
