Info for PHY ID
This command is typically intended for replacing a bad drive. This operation
must not be used while there are outstanding I/O requests to the lun_dsf or
to any LUNs under the new_hw_path. If the -f option is not specified, sasmgr
displays a warning message before proceeding. Otherwise, it suppresses the
warning message and executes the command.
NOTE:
This command does not allow a persistent device file or the new style
hardware path to be specified with the old_dev and new_tgt_hwpath
qualifiers. For persistent device files, please use the io_redirect_dsf
command. See the io_redirect_dsf(1M) manpage for more information.

the command. Otherwise, it suppresses the warning message and executes
the command.
The following qualifiers must be specified with the set_attr command:
•

•
state
•
raid_vol
Use this set of qualifiers to change the state of the volume based on the value
specified by the state qualifier and the volume specified by raid_vol. If
the -f option is not specified, sasmgr displays a warning message before
continuing the command. Otherwise, it suppresses the warning message and
executes the command.
•
raid
•
raid_vol
•
rebuild_rate
