RE: Help with Network Appliance configuration ???

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. Boa Sorte, Paul Benn Network Appliance -----Original Message----- From: Alexandre Gomes (r7043c) [mailto:r7043c@email.sps.mot.com] Sent: Tuesday, June 29, 1999 5:53 AM To: lista de discussao Subject: Help with Network Appliance configuration ??? Hi, I'm installing budtool( version 4.5) on a Solaris machine to operate a jukebox robotics connected to the Network Appliance ( F230) to do backups. On the installation he gaves the following message ( I will use NDMP protocol) : The spt and sjb drivers are capable of communicating with devices on any SCSI bus attached to this host. These drivers need to know on which bus the jukebox is attached. The first bus (e.g. esp0) is number 0, the second bus is number 1, and so on. Only a number between 0 and 7 will be accepted. Please enter the number of the SCSI bus for the jukebox: Could someone help me, How I discover the SCSI bus where my jukebox is connected on Net App.I execute the sysconfig on the NDMS and it says : paje> sysconfig -v NetApp Release 4.3.4: Wed Apr 22 16:25:06 PDT 1998 System ID: 0016785098 slot 0: System Board 90 MHz (NetApp System Board Ia rev-b) Firmware release: 1.9_i Memory Size: 192 MB slot 0: SCSI Host Adapter 0 (QLogic ISP 1040B) Firmware Version 2.26 Clock Rate 40MHz.

FYI, posts made to the list between Sunday evening and just now (10am EDT) will not be appearing in the toasters archive. I seem to recall there being a few posts, but not many. This past weekend was spent moving our servers to our new office building. In the move a few changes were made, and a few things broken. :-) K.

I would have to say yes, it's *possible*, but the controller would have to fail in a very odd way; not simply not responding the some requests (that would be caught), but executing some and not others (but claiming it did) or misordering commands or something like that. I would think this kind of error would be very rare. Perhaps the controller you had is particularly prone to those sorts of errors; one advantage of Netapp is you're using controllers they themselves have partially designed and tested. Bruce

Re: Increasing "maxfiles" and its effect on performance

Very little, unless you set it to an extremely high value that is far, far more than you need. (Like, I dunno, 1 billion?) Even then I doubt it would be very noticeable unless the filer were heavily loaded. If you are running out of files on the filer (which is not unusual if the default setting was conservative and you've added a lot of space), you shouldn't think twice about upping the maxfiles value. I would guess (one of the Netapp WAFL experts could correct me on this) that since maxfiles reserves some space in the filesystem for metdata, that slowly increasing maxfiles over time (rather than in large increases at once) might "fragment" the metadata file across the filesystem, thus hurting performance somewhat. But then I seem to recall that even when you increase maxfiles, this space is not necessarily allocated right away, so maybe it doesn't matter and they'll only grow in a fragmentary fashion anyway. (Fragmentation is not really much of a problem on Netapp's anyway and is only really noticeable on very large files.) Bruce

Increasing "maxfiles" and its effect on performance
by Mike Ball 25 Jun '99

What affect will increasing the "maxfiles" have on the read/write performance on a volume? We are currently running Data Ontap ver 5.2.2P1 on a F740.

Disk Controller Failures
by Mingway Huang 25 Jun '99

25 Jun '99

Hi there, We recently encountered a disk controller failure on one of our data servers (not on our Netapp). The problem was that this failure was not a complete failure of the drive itself, but rather the controller started to die slowly. (i.e. handles some request sometimes and other times who knows?) As a result, this caused our entire filesystem to become corrupt and we lost some of our data as a result. Although this filesystem was mirrored, this did not help us at all, as it was considered a logical error in the filesystem and not a hardware problem. My question is that should this occur on a Netapps (this may even apply to any other Enterprise server) would it cause the entire filesystem to go corrupt and cause partial or complete data loss as in this case?

RE: list of file lock types
by Hawley, Rob 23 Jun '99

CIFS locks have two parts; basically "What I want to Do" and "What I am going to prevent others from doing". "What I want to Do" EXEC == read + execute R&W == read + write Read read Write write "What I am going to prevent others from doing". DenyAll exclusive access to file DenyR others cannot read the file, but can write DenyW others cannot write file, but can read DenyN others can read or write the file DOS special compatibility mode for DOS ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > mailto: hawleyr(a)netapp.com <mailto:hawleyr@netapp.com> US Mail: Network Appliance Inc. > Phone: 408-822-6661 2770 San Tomas Expressway > FAX: 408-822-4521 Santa Clara, CA 95051 -----Original Message----- From: Todd C.

RE: quick question about dumping snapshots
by Melvin, Grant 23 Jun '99

23 Jun '99

Hi Jason, > Hmmm... It seems to be _another_ NDMP bug. The first example I > sent out was generated by running the dump from BudTool via NDMP. This is a bug and its been filed as 15998, the following description will be online tomorrow: TITLE: ndmpd updates the dumpdates table incorrectly when dumping pre-existing snapshots DESCRIPTION: In 5.3, if a dump of a pre-existing snapshot (such as /vol/vol0/.snapshot/hourly.0) is used, the dumpdates table is updated without the ".snapshot/hourly.0". It should only show: /vol/vol0/ 0 Sun Jan 1 00:00:00 1999 However, ndmpd prints out /vol/vol0/.snapshot/hourly.0 0 Sun Jan 1 00:00:00 1999 to the dumpdates table and doesn't modify the dump name to "/vol/vol0/". Sorry for the inconvenience. Cheers, Grant

help on quotas
by Jason Middlebrooks 23 Jun '99

23 Jun '99

I have the following happening. Overview: F630 running OnTap 5.2.2 using CIFS. Two volumnes vol0 and usr. The volume usr contains everybody home directories using cifs.home_dir. I am using a PDC for authentication and I am not using the passwd or group files on the filer. Whats Happening: I have a quota file with the following entries: /vol/usr/usrhomes/cnievesad user@/vol/usr 5G 20K * user@/vol/usr 80M 15K # Default home directory quota /vol/vol0/trafficker tree 5G 15K /vol/vol0/prod tree 2GB 15K /vol/vol0/tsa tree 4GB 50K I have created a new user called msmith and I created the following directory /vol/usr/userhomes/msmith. msmith can map to his directory fine but when I try to create a new folder or file I get the following messages on the filer: Wed Jun 23 14:34:06 GMT [wafl_lopri]: uid 65534: disk quota exceeded on volume usr. The default home directory quota has working in the past at least when I was at OnTap 5.0 Any ideas??? Thanks in advance Jason
