3590-B1A to 3590-E1A, Part II
Ok, I've looked over some more info and some comments that I've got. We are running (1) 3494 library with (2) 3590-B1A drives attached to an IBM Netfinity 7000 M10 server running WinNT4 SP5, TSM version 3.7.3. I'm thinking of having the CE convert both drives to the E1A version on the same day. When he gets done then I would do the following: 1. UPDATE DEVCLASS 3590CLASS FORMAT=DRIVE 2. DELETE DRIVE IBM3494A MT0.0.0.2 -FOR THE FIRST DRIVE 3. DELETE DRIVE IBM3494A MT0.0.0.3 -FOR THE SECOND DRIVE 4. DEFINE DRIVE IBM3494A MT0.0.0.2 DEVICE=MT0.0.0.2-FIRST DRIVE 5. DEFINE DRIVE IBM3494A MT0.0.0.3 DEVICE=MT0.0.0.3-SECOND DRIVE 6. Run a SQL script to get a list of tapes in the library that would need to be made readonly: select volume_name from volumes where stgpool_name='TAPEPOOL' 7. Do an UPDATE VOLUME X ACCESS=READONLY for each tape on the list. If I understand this process correctly, as the tape reclamations are done on the tapepool tapes they will move from a readonly status to a readwrite status and then become usable with the greater capacity. Also, as the copypool tapes come back from offsite they will also then be usable with the greater capacity. Am I at least close on my thinking??

Re: 3590-B1A to 3590-E1A, Part II
Rather than SQL scripts, do: update volume * access=readonly wherestg=TAPEPOOL This will update all non-scratch tapes. As the tapes are emptied, they will return to scratch / readwrite Regards, Gareth Jenkins "Tyree, David" david.tyree@S To: [EMAIL PROTECTED] GMC.ORG cc: Subject: 3590-B1A to 3590-E1A, Part II 04/05/01 01:59 PM Please respond to "ADSM: Dist Stor Manager" Ok, I've looked over some more info and some comments that I've got.

3590-B1A to 3590-E1A
We will be doing an update to our tape drives around the end of the month. I've looked over the older messages concerning this and all I saw was a dilemma about microcode levels. The messages were dated the last part of 1999, so I would image that the microcode has been updated since then. Here's the situation, we are running (1) 3494 library with (2) 3590-B1A drives attached to an IBM Netfinity 7000 M10 server running WinNT4 SP5, TSM version 3.7.2. We currently have about 250 "J" tapes on hand and we will have those used up in about 60-90 days. That's why we are going with the newer drives. We understand that they have 256 tracks on the new drives as opposed to the 128 tracks on the older ones. Thus doubling our tape capacity. Now the question, we have been told that the new drives will read and write to our current "J" tapes just fine. They will read the 128 tracks and then as we do our tape reclamations it will then write to the tape on 256 tracks. As we cycle in the older tapes in for reclaiming they all become 256 track at some point. We generally have about 5-6 tapes a day go offsite and about that many returning each day as well. Is this correct?? I also understand the E1A drives will work the best if we go to the newer "K" tapes, however you can't have "J" and "K" tapes in the library at the same time for some reason.

Not true we have a mix of both "J" and "K" tapes in the same 3494. Not a problem. Both will coexist just fine.

Is this correct?? I can't verify how many of your tapes go offsite each day, but can verify that J tapes that are re-used get written as 256-track in 3590E drives and thus double your capacity. I also understand the E1A drives will work the best if we go to the newer "K" tapes, however you can't have "J" and "K" tapes in the library at the same time for some reason. Yes, you can, and many of us do. Refer to the server README file for particulars on upgrading your drives in a TSM environment. Richard Sims, BU
Re: 3590-B1A to 3590-E1A
Ditto. No problem with J's K's together. And the 3590E's read and write the J's just fine. -Original Message- From: Richard Sims [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 04, 2001 1:39 PM To: [EMAIL PROTECTED] Subject: Re: 3590-B1A to 3590-E1A Now the question, we have been told that the new drives will read and write to our current "J" tapes just fine.

Re: 3590-B1A to 3590-E1A
With regards to reading and writing on old tapes: If you are using collocation then it is important to make all your current tapes in the collocated pool read only. You will NOT be able to write to tapes which have been written in 128 track format. I believe that if you attempt to write to any of these tapes the tape will become read only or unavailable (we upgraded over a year ago, and I don't remember which.). Anyway, if I were you, after the conversion I would change all of you collacted tapes access mode to read only. I would then increase the maximum number of scratch volumes for the pool. Once this is done I would suggest kicking of: 'move data volume name stgpool name' for each of the volumes that you changed to read only. I used a ksh script with awk to get the volume names that I wanted to process. Then I ran the scripts . P.S. Make sure you delete the drive definitions and recreate them for the new drives, otherwise the new drive will write in the old 128 track format ... If you have any other questions you can contact me directly ..

Re: 3590-B1A to 3590-E1A
Yes. So if you upgrade your drives from B's to E's, you get double the data on the tape (10 GB native at 128 tr, 20 GB native at 256 tr.) If you upgrade your cartridges from J's to K's and write on them with the 3590E's at 256 tr, you get twice as much tape in the cartridges, so it doubles again, to 40 GB native. So with compression, you will get over 80 GB on the cartridge. -Original Message- From: Tyree, David [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 04, 2001 3:34 PM To: [EMAIL PROTECTED] Subject: Re: 3590-B1A to 3590-E1A Will the 3590E write to the J's as 256 tracks? -Original Message- From: Prather, Wanda [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 04, 2001 2:23 PM To: [EMAIL PROTECTED] Subject: Re: 3590-B1A to 3590-E1A Ditto.
