HP SureStore E SAN Manager LUN Management Solaris Installation Guide

40 A Device Cannot be Disabled from a Solaris Node
A Device Cannot be Disabled from a Solaris Node
Symptom Cause/Solution
When unassigning a
device from a Solaris
node, the Windows
NT administration
node displays a
Disable Device
Failed
error
message.
The device contains a mounted file system that is in use. Stop
any processes that are using the file system, unmount the device,
then unassign the device with the SAN Manager administration
application.
The device is configured to be used with third-party storage
management software, such as Solstice DiskSuite or VERITAS
Volume Manager. SAN Manager has no way of telling a third-
party storage management application that a particular device
needs to be removed from its configuration. Before unassigning
device(s) in SAN Manager, manually remove them from the control
of third-party storage management software.
The device is in use by an application that accesses it directly.
SAN Manager has no way of knowing what program is using
the disk in question, or how to make it stop without interrupting
what may be a critical process. Before unassigning this type of
device, shut down the program that is using it and unmount the
device.
