To change the LUN assignments using the CLI, use the
present
command described in “Modify Volume–
Host Mappings” on page 82, adding the
: <lun>
option after each host name. For example, the following
command changes the LUN through which Volume03 is mapped to host Prod02 to LUN7 from whatever LUN
was previously used:
present --volume=Volume03 Prod02:7
Mappings do not have to be removed before changing a LUN.
Re-size LUNs
The ISE supports LUN re-sizing, expansion, and contraction in place without first copying data to another
volume.
LUN re-sizing in the ISE is done in multiples of 1GB by adding to or subtracting from the currently highest
numbered logical block address. During LUN re-sizing, independent of the LUN re-size amount, host I/O to the
volume is momentarily paused (no more than ten seconds).
A re-sizing process cannot be aborted once initiated, cannot be undone, and the original presentation persists.
Presentation changes must be done manually after the LUN is re-sized. The re-size process is unaffected by
controller failovers and reboots. The ISE generates an SNMP trap (if enabled) for LUN re-size processes upon
completion and in the event of a failure (such as insufficient space or target LUN being inoperative).
LUN Expansion
When the expansion process begins, the ISE reserves enough space to complete the expansion.
LUN Contraction
The operating system volume contraction must be completed before a LUN contraction is attempted. Not all
operating systems, file systems, and databases support volume contraction. Refer to the operating system
documentation for recommended procedures prior to volume contraction.
Note.
Improper use of LUN contraction results in data loss.
