Recommended formula to use to determine "maxfiles" size.
by Mike Ball 01 Jul '99

01 Jul '99

Can anyone recommend a formula to use to determine "maxfiles" size? We are using mostly 64k file size html text docs.

Four Simple Steps Are Required Here> 1. Read the tape library manual 2. Read the netapp manuals. 3. If you still have questions - check the SCSI FAQ at http://www.cis.ohio-state.edu/hypertext/faq/usenet/scsi-faq/top.html 4. Finally, if you still have questions pay a qualified engineer to install it for you. JT

The problem is that the cable has 68 pins and the SCSI 0 of my Network Appliance has 50 pins. I must use a cable that convert of 68 to 50 pins or what I have to do ????

LDAP and Unix
by Lex Beijk 30 Jun '99

Hi everybody I am working at TNO-FEL, a physics-lab in the Netherlands. We are setting up a multi-platfom environment with a LDAP-directory server for integrated user and resources management. Working with the Netscape directory-server we can replicate between NT and LDAP for the Netscape environment. I have done some testing with the Luke Howard LDAP-client for Unix (Luke also has written rfc2307, by which you can map NIS attributes on LDAP attributes) to run NIS requests over LDAP. It is running very well. My questions to you are: - how can I integrate te Netapp-filers in this (They don't have a LDAP client YET) - Is there anayone else, who has done something with LDAP and Unix ( and maybe Netapp filers) - Who will migrate to LDAP-based directory service' when it is available. Pls, give some reply to this group. Thanks ...

What model filer is this? If it has a 50 pin connector then it's supporting a narrow bus only. If you use a 68 to 50 pin converter then physically it'll make the connection, but data speed will suffer. A 50 pin connector supports only an 8 bit SCSI bus while a 68 pin supports a 16 bit SCSI bus.

ufsrestore
by chris＠cecil.muscat.com 30 Jun '99

30 Jun '99

Yesterday I dumped a load of data from our filer to a DLT7000 using: dump 0lfbn nrst0a 63 spong / then typing the directories to backup. Tape started rolling and after dumping the right amount of data stopped. Took the tape down to a 3rd party to do some benchmarking on our data and tried to restore it on a solaris 2.6 box but whatever we tried we couldn't get the data off. At one point we managed to get a directory structure but no files off. As far as I can remember we decided that the correct options were: ufsrestore -xfb /dev/rmt/1u 126 does that seem plausible? I'm now a little concerned that I wouldn't be able to restore my data via a sun box should the worst happen. -- Chris Good - Muscat Ltd.

Sadly, most customers do not share this sense of wonder, perhaps precisely because it is an "appliance" that is supposed to "just work" like your toaster or your telephone. Not that we haven't had our problems with filers, but for the most part, Netapp maintenance is effortless, amazing considering the amount of stuff that has to happen in behind the scenes. -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't"

Sr. Alexandre, You appear to have the tape library connected to the wrong SCSI bus (the card in slot 9). It should be connected to the onboard SCSI which is bus 0.
