Replication across Domains!!
by Pramod 18 Apr '02

18 Apr '02

Hi All, I have two filers replicating data. The two filers are in different domains. Now if one of my site goes down( along with the PDC and BDCs of that domain), how will I be able to access the data of the mirrored volume on the remote site after breaking the mirror....... as the files will have permmissions of a different NT Domain. I cannot create NT 'Trust' or have a BDC of each domain on the remote site. Is there anyother way of doing this. Can I reset all the permissions on the mirrored volume in the remote site in case of a 'site outage', so that I can access the data there. Thanks Pramod

Using ADSM/TSM to backup filers
by Mark Allen 18 Apr '02

18 Apr '02

Is anyone using ADSM/TSM to backup there filers? If so, how are you doing it and what version of TSM are you running. I'm evaluating a filer and I'm looking for different ways to backup the filers using ADSM down to the file level. -Mark

RE: rescan SCSI bus?
by Drew O'Donnell 18 Apr '02

You are correct, this will only work if the DLT drive is located in the fcal loop, which is not likely unless John is using an SCSI/FCAL bridge. We are using NDMP fiber channel backup, and had problems reconnecting without rebooting the filer.

Not as farfetched as you might think. It happened to us within the past couple years. I don't remember the details, but we had to bypass the failed shelf to even get the filer back up. _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ Don Cunningham - UNIX SysAdmin _/ Progress Software Corp. _/ _/ don.cunningham(a)progress.com _/ 14 Oak Park _/ _/ (781)280-4252 _/ Bedford, MA 01730-1485 _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ "Wherever beer is brewed, all is well - whenever beer is _/ _/ drunk, life is good." -Czech proverb _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/

Dead Disk Shelf for One of The Clustered Filer
by Nicholas Chua 18 Apr '02

18 Apr '02

Hi, Is it possible for the disk shelf to completely fail? By this I don't mean the power supply or fans because those are redundant and replacable. I thinking more of a board/ic failure or maybe shelf firmware bug that can completely knock out a disk shelf. If there is a remote possibility of this happening, then I figure the partner would not be able to take over the failed filer through channel B as well under a cluster environment. Am I being too paranoid? I'm looking for something like the Mean Time Between Failure (MTBF) for the Disk Shelf if available, be it FC9 or DS14. Any input would be greatly appreciated.

Hi! Has anyone ever seen a mapped drive, off a nteapps completly vanishing from a PC? We use win2k and map a drive to U:. However, on some machines the users report that this drive just disapears. If they re-run the logon script it reappears, and other CIFS shares stay in place on the machine..any ideas?
