88 Secure Path v3.0C for Linux and Linux Workgroup Edition Installation and Reference Guide
# spmgr restore -r WWNN
Restores a preferred path to the indicated storage system.
Syntax:
# spmgr restore -r WWNN
Example:
# spmgr restore –r 5000-1FE1-0010-5B00
The quiesce command
Quiescing an object means to:
■ Move all active I/O from an object to an alternate path.
■ Mark all paths to the object as quiesced to temporarily remove the object from
use.
The objects that are supported for v3.0C of Secure Path are adapters and
controllers. Also, quiescing individual paths is supported to allow other fabric
infrastructure, such as switches, to be removed and replaced.
Note: Path verification is not performed on a quiesced path.
Syntax:
# spmgr quiesce-a HBA
-c controller_serial_number
-p path_instance
# spmgr quiesce -a HBA
When this command is invoked, spmgr will move all active I/O using this HBA
to paths available on other HBAs. The paths of the specified HBA will then be
marked as quiesced, and no further I/O will be sent along that path until the HBA
is returned to service with the corresponding restart command.
These actions may be verified by issuing the
# spmgr display –a HBA
command to view the current path state.
