If you make absolute links (beginning with a leading slash) you need to consider how the filer is going to resolve those since the UNIX exports and CIFS shares may be coming from different paths. The /etc/symlink.translations file is used to help the filer interpret absolute symbolic links. If pchome is full of links to another directory on the filer and you use relative links you should be fine. You also need to enable symlinks with the cifs.symlinks.enable option. /vol/vol0/pchome bob -> ../home_systems/bob jim -> ../home_software/jim /vol/vol0/home_systems bob /vol/vol0/home_software jim Dennis Haag -----Original Message----- From: Moshe Linzer [mailto:moshel@taux01.nsc.com] Sent: Wednesday, June 21, 2000 8:09 AM To: toasters(a)mathworks.com Cc: David.Lockwood(a)benettonformula.com Subject: Re: Filer (F740) with CIFS and NT Terminal Server Edition (Metaframe) We are actually doing this slightly differently.

RE: CIFS file locking problem
by mark.muhlestein＠netapp.com 21 Jun '00

21 Jun '00

The way it works is that if a CIFS client has open files but no command has been received at the filer for 10 minutes, we send a keep-alive NETBIOS message. That then goes through the normal TCP timeout logic, which will normally take 520 sec or so. That means the total elapsed time for a non-responsive connection to timeout is just under 20 minutes. If you can verify that the locks are still present after more than 20 minutes, please let us know. We'll have to take a packet trace to see what is going on.

NFS connection from Novell Netware 5

Does anyone have experience of using a filer and NFS mounting a directory from a Novell NetWare 5 server ? Is it as simple as adding the NFS client to Netware 5 and following the normal NFS mount process ---------------------------------------------------------------------- For further information on Benetton Formula 1 visit our web site at www.benettonf1.com.

Backup Technology
by Derek Kelly 21 Jun '00

21 Jun '00

Has anyone on the list had experience (good or bad) using Overland Data SANPiper (a SCSI-to-Fibre Channel bridge technology) or Vixel switches in thier backup strategy? If so, please let me know. We are looking at implementing one of these solutions and are interested in any opinions or possible caveats we might hit.

Hi, We are using such a setup from long time. You create a qtree or directory /vol/volname/home where all the home directories resides. Then you access the home directories throught the automounter maps as userid filer:/vol/volname/home/& Then set an option on the filer cifs.home_dir /vol/volname/home/ This works fine if the userid of the unix and NT matches or else you may have to edit the /etc/usermap.cfg. kind regards Bhaskar G Philips Semiconductors, #3, Sterling Square,Madras Bank Road, Off St Mark's Road,BANGALORE-560 001.

There is two ways (at least) to do this: 1* Map "local" drives in the ICA Client, that enables the ICA Client to read files on the mounted filesystem on the HP-UX boxen 2* Use CIFS on the filer, and make shares for each user that are accessed by the Terminal Server >>>>>>>>>>>>.rune PS! is 12000 NFS ops on an F740 a lot? -- Rune Bakken System Administrator Nextra, a Telenor Company

Tape libraries
by Gordon Keegan 21 Jun '00

21 Jun '00

The only supported tape drive, stacker and library chart that I can find on NOW is dated 11/98 and doesn't seem to list much beyond DLT4000, DLT4700, and DLT7000. Is there a newer list of supported tape equipment somewhere?
