cplv question

[selan]

Hi All,

I have 2 fiber attached disk systems, and want to migrate raw data from one to another.
I can not use disk to disk mirroring (on SAN side) because of licensing issues.
I can not use AIX volume group mirroring due to some VG restrictions.
So, I have decided to use AIX cplv command. I have looked at /usr/bin/cplv command and saw that it does copyrawlv with 128KB blocks. This increases the migration time.

Now, the question is why it is 128K, can it be greater ?
And why is it hard-coded in the cplv command ?

Thanks in advance,

Can you not add the disk into the same VG and use migratepv?
