EMC – Check on a RAID Group’s defragmentation progress with naviseccli

Posted on by

For those of you still using RAID Groups on the CX4, you’ll know that you sometimes need to defragment them to get a contiguous amount of free space, particularly if you’ve unbound LUNs in the group that sit between other, remaining LUNs. If you kick off a whole bunch of defrags and then want a quick way to check the progress, why not use naviseccli? The getrg option is the one you want to use in this example.

naviseccli -h 256.256.256.256 getrg -prcntdf

The output will look something like this:

RaidGroup ID: 0
Percent defragmented: 100
RaidGroup ID: 1
Percent defragmented: 100
RaidGroup ID: 2
Percent defragmented: 100
RaidGroup ID: 3
Percent defragmented: 1
RaidGroup ID: 4
Percent defragmented: 1
RaidGroup ID: 5
Percent defragmented: 100
RaidGroup ID: 6
Percent defragmented: 2
RaidGroup ID: 7
Percent defragmented: 1
RaidGroup ID: 8
Percent defragmented: 100
