Re: 3590 Tape Drives
Is anyone monitoring the drive internal logs or looking at them. It sounds like the drive pressure is out of alignment in all the drives. This could be because the CE you have has no idea what they are doing. Paul D.

Re: 3590 Tape Drives
Make sure IBM has removed the cleaner blocks from the drives. If tapes are being eaten, I'd say it is probably poorly adjusted pressures in the drive somewhere or something isn't in proper alignment BUT I'm NOT an IBM technician so I really shouldn't say... In 7 years across 7 ATL's with 7 year old tapes (for the most part) we are still going strong !

Re: 3590 Tape Drives
You can have one drive going wrong. I can even imagine two can have problems simultaneously. But if all four together have a problem it is hard to believe. Did your IBM CE verified the robot. Ask for same problem re-open instead of open as new problem. As Wanda said shout, demand, escalate the problem. You've paid a pile of money for those drives they MUST work, period. Upgrade may help and may not, who will have to explain why you spent another pile of money for upgrade.

Re: 3590 Tape Drives
I'll 2nd that on the cleaner blocks. We had many problems with media errors until we *made* the CE remove the blocks. He shook his head and said Alright, it's your system..Media errors just about vanished. In 6 years of 3494 with 3490e and 3590 drives, I have only had 5 that were destoryed by the drives. Now if you want to count the number tapes destroyed by operatorswell, that's a different story!

Re: 3590 Tape Drives
Just to make it clear: the drives do not fail at the same time, but one after another in a certain period. Today it can be rmt1 which has a problem, next week maybe rmt2, another three weeks later rmt0 and so on Kind Regards Martina Sawatzki
Re: 3590 Tape Drives
Phil, please clarify.did you completely replace the B1A drives with new E1A drives, or did IBM convert your existing B1A's to E1A's with an upgrade kit?

We were running them 23 out of 24 hours every day. We cured the problem by going to the E1A and adding more tape drives. The different between the drives is the B1A are 128 track, the E1A are 256 track and the H1A are 384 track drives. You gain one third capacity for every increment you go up on your drives.

Re: 3590 Tape Drives
Actually, there are 2 speeds to be concerned with. Data transfer from the host to the 3590 controller. SCSI, depends on length and type of connection (34 was the top on SCSI E1A). 40 MB/sec on FC E1A advertised, but I have seen higher (FC) 70 MB/sec on FC H1A advertised (FC) Then, compression voodoo happens so less physical bytes are written to tape.

Re: 3590 Tape Drives
We were in the same situation. Also couldn't get 10-20% of my tapes to initialize. Lots of errors and problems. IBM would run their diagnostics and find nothing wrong. They also replaced parts, i.e. the heads, cleaners, etc. Contacted iMation. They said the problem was with the tape drive microcode levels. They told me what minimum level to get to. Had IBM come in and upgrade the microcode and the software levels on various other components of my 3494. Most if not all of my problems went away. I was able to initialize the tapes that previously wouldn't.

Re: 3590 Tape Drives
We have 2 3494's with a total of 15 3590 drives attached to a mainframe, and to Windows TSM. We started with the B drives, upgraded them 18 mo ago to E drives. Performance/availability of both drive models has been superb. (We upgraded for capacity, not availability issues.) We occasionally see a tape dismount failure. We have also had the brushes wear out and have to be replaced. But when the CE fixes that sort of thing, it stays fixed. We definitely see less than 1 service call per year, per drive, not repetitive problems. The 3590 drives (B or E, I have no experience with H yet), along with the STK 9840's, are the most robust drives on the market today (well, except maybe those things in the black boxes on airplanes) You should NOT be having ANY repetitive hardware problems with them. Most repetitive problems with this type of drive turn out to be backlevel microcode, or bad media. You should manage your media aggressively - make sure you keep a list of which tape is in the drive when you have a problem, and if the same tape shows up twice remove it from the 3494, at least until this problem is resolved. Yell at your CE, a lot. Make him/her check the microcode levels. Call the district CE manager and demand an explanation of why you are continuing to have problems with IBM's premier enterprise class drive that works great for other sites. Make them call in the district technical specialist. Keep him/her on site until the problems go away. Demand that if they can't fix the drives, they replace the whole thing (that usually gets their attention). Sometimes, you have to yell if you aren't getting sufficient service. And sometimes, your CE just needs some help getting the problem escalated in his management chain. BUT, these drives should work. You shouldn't have to upgrade to get rid of hardware problems. -Original Message- From: Martina Sawatzki [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 19, 2002 5:50 AM To: [EMAIL PROTECTED] Subject: 3590 Tape Drives Hi, We are working with a 3494 IBM silo with 4 drives - 3590 type B - which is connected to a RS/6000.

I experienced some problems with the B1A drives also, but we caused some of our own problems. We were running them 23 out of 24 hours every day. We cured the problem by going to the E1A and adding more tape drives. The different between the drives is the B1A are 128 track, the E1A are 256 track and the H1A are 384 track drives. You gain one third capacity for every increment you go up on your drives. We current have a total of 30 E1A tape drives between the open systems backup and the MVS systems native drives.

Re: 3590 Tape Drives
Dave, I recently upgraded one of my clients from B's (SCSI) to H's (fibre) on an AIX server. We had some initial quirks, which seem to have been cured by firmware. Aside from that, we have seen an increase in the number of tapes getting flagged readonly, which we expected due to the increased track density. We have NOT seen any significant increase in speed, despite the marketing claims. We are, however, getting 3X as much data on a tape. -Lloyd On Tue, 19 Nov 2002 15:13:36 -0800 Pearson, Dave [EMAIL PROTECTED] wrote: Is anyone using the H1A drive and if you do... How is it? David C.

Re: 3590 tape drives

Because they were bought one year ago, they don' t have the facility to read/write the extended-length-cartridges, so we use the normal cartridges with 20 GB uncompressed. Now we plan to upgrade those drives (IBM-upgrade-Kit) so that they can handle the extended-length-cartridges (40GB uncompressed).

Re: 3590 tape drives
The drive can physically tell what type of cartridge is in it. The Extended Length upgrade adds the ability to read/write the longer tapes, but doesn't take away any other capabilities. If you look at the label end of a 3590 tape, there are two plastic inserts below the label (if the gear drive side is down). There are notches taken out of these inserts which allow the drive to tell what type of tape it is. CE cartridges, Cleaning tapes, 3590, 3590XL, all have different codes with the notches.
