Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

-l lun { on | off } |
--led lun { on | off }
lun
Is a decimal LUN number.
Print Command
Displays a device LUN table entry from kernel memory. If no LUN is specified, display the entire
device LUN table. The syntax is:
-p [lun]| --print [lun]
If no lun is specified, find all devices.
Renumber Command
Renumber an old enclosure base LUN to a new value. This command fails if any device in the old
enclosure has an I/O operation outstanding or there is already an enclosure with the new LUN
value. The syntax is:
-r old new | --renumber old new
old
Is the old LUN value.
new
Is the new LUN value.
If any device in old enclosure has an I/O outstanding or there is already an entry for new, returns
an error. Confirms with "Are you sure?".
Scan Command
Scan all HBA ports for new devices. This option should be used after you create new ESS LUNs
or new virtual tapes in a VTS so that the CLIM sees the new device LUNs. The syntax is:
-s | --scan
Startover Command
Clears the device LUN table, enclosure table, and enclosure LCDs. If the existing enclosure table
is significantly different from what is desired, then --startover followed by --approve may
be simpler to use than several --delete and --renumber commands. The syntax is:
--startover
Unblock Command
Unblocks lunmgr so that all subsequent lunmgr commands are allowed. If multiple --clear commands
have been entered, then an equal number of --unblock commands must be entered before other
commands, including --update, are allowed. The syntax is:
--unblock
Update Command
Finds new storage devices and assigns new device LUN numbers to them. The verbose option
displays the device table and devices present. This option is used internally whenever devices are
added or removed, so it is rarely necessary to use --update interactively. The --approve and
--unblock options automatically perform an --update.
• Recognizes and ignores non-storage devices.
• Recognizes known devices by stable attributes and updates volatile I/O address.
