Displaying disk devices in SMH
Displaying disk devices in SMH
To display disk devices in SMH, select Tools > Disks and File Systems > Disks.
The Disks tab of the HP-UX Disks and File Systems Tool screen lists the system’s
disk devices. To switch between legacy device names and new agile device
names, click on Toggle Global Device View:
In the legacy view, all paths to a device are listed using the old-style c#t#d#
naming convention that is used in the /dev/dsk and /dev/rdsk directories.
In the agile view, a device is listed according to the name of its persistent device
file in the /dev/disk and /dev/rdisk directories, using the disk## naming
convention.
The number of paths to a device is indicated in the “Paths” column in both
views.
When VxVM is installed on the system, the “Use” column in SMH indicates
whether a disk is under LVM or VxVM control, or whether it is unused.
If a VxVM disk is online and part of a disk group, the disk group name is listed
under the “VG Name” column. If a VxVM disk is initialized, but not yet part of a
disk group, it is listed as “unused” under the “Use” column.
A more detailed description of a disk’s properties can be obtained by selecting
the radio button to the left of a listed device.
Figure 4-1shows a sample Disk Devices screen for a system with several VxVM
disks, one LVM disk, several unused disks, and a DVD-ROM device. The VxVM
disks are all in the mydg disk group. The detailed view of disk30 shows that it
has two paths with the legacy names c5t0d7 and c7t0d7.
