Is it possible to get info from counters"unaligned_writes" and "write_align_histo:" via the DFM CLI?
I'm trying to find an easy way to build a list of all LUNs that are missaligned (ie. writing in histo other than 0)

Not exatly to display those counters but you can get misaligned LUNs by using this command:
dfm perf diag troubleshoot -a controller_name -s "start date and time" -e "end date and time"
Format for date and time is
That's useful info.
I managed to get the counters I wanted out, just need to work on building them into a more usefull output now.
dfm perf export counter add lun:unaligned_writes
That will add the "lun:unaligned_writes" to the output of dfm perf export
