Yes they would be nice. Rob Berendt ================== "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."

That's why I say the number of disks in my experience did not seem to make much difference. DST apparently is working on all the drives concurrently. Also, my statistics included the time to "unload" the data from the drives onto other drives in the current ASP. I'm assuming you won't be doing that(?). It seems that what you are doing would not be all that uncommon. Any chance you could get Rochester to take a guess at it? I went to a COMMON session a few years ago where the speaker was an IBM Disk Processing expert. If you are interested I could try to dig out his contact information.

Nervous about that data though. I don't have 75 hours to spend. Anyone else have some samples? I guess we should have kept our stop watches handy the last several times we added dasd.

Like FORMAT C:? This may not be relevant, but we recently moved some disks from one ASP to another on our single AS/400. We actually did this is three passes. Each pass took between 45 and 60 minutes. The size of the disks (4 or 8 GB), the speed of the disks, or the number of disks (1,2 or 3) did not seem to make much difference. Another bit of worthless information: We also added a single new disk drive (8 GB, 10 k rpm). I did not watch the clock when it we added it to the RAID set, but I'm guessing it was about 20 minutes. Two days later we added it to an existing ASP. That took another 30 minutes running under DST. Phil Subject: How long to initialize disk?

Any estimates on how long it will take to initialize the following: qty model 30 6717 45 6718 Rob Berendt ================== "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."
