Re: [BRUServer-Announce] Mac OS X 10.4.10 Announcement...



Did your tape drive problems seem to coincide with an update to 10.4.10? I use BRU also, and I'm running 10.4.10. As far as I know, I'm not running into any of the problems that they describe.

Every week I do 1 full and 6 incremental backups to a firewire 800 disk, then I upstage to a SCSI autochanger (Exabyte 221L). My backups aren't particularly fast, and I did contact BRU about that, and they pointed me to the alleged 10.4.10 problems. I went and took a look at my logs from before the update to 10.4.10, and there really isn't an apparent difference in speed from before and after, so I'm not sure I buy the whole 10.4.10 has firewire, USB and SCSI problems line.

My backups and restores are working, so I'm not going to downgrade.

this issue..


We have a older G5 XServe with XRaid connected via Fibre Channel and an Adic
Scalar 100 LTO-2 tape unit connected via SCSI.


We have been seeing some issue with our tape unit lately and looking for
suggestions on a fix or work-a-round.
Looks like Apple is taking their time on this......


BRU suggest this:

To resolve this issue, we strongly suggest that you downgrade to
10.4.8, as 10.4.9 has been known to exhibit the same type of symptoms.

My question would be if we select to downgrade to Mac OS 10.4.8,
What would be the Best method to do downgrade to Mac OS 10.4.8 ?

An Important Note for Mac Users of BRU Technology Under Mac OS X

Since the release of 10.4.10, there are a number of issues that have
surfaced with writing to tape and disk devices.  For this reason,
10.4.10 is not compatible with tape devices connected to Mac OS X
10.4.10 via SCSI, FireWire, USB, SAS, or Fibre-Channel.

This is not a BRU Server software problem, but rather an Apple Mac OS
X problem when using any type of software that communicates with tape
devices.

Other problems with XRAID, Xsan, and other disk devices communicating
over these channels may also be realized.

To resolve this issue, we strongly suggest that you downgrade to
10.4.8, as 10.4.9 has been known to exhibit the same type of symptoms.

We apologize that we did not make the announcement sooner, however, we
believed that 10.4.11, which fixes this problem, would be released
much sooner than now.  As of this announcement, 10.4.11 has yet to be
released, nor has there been an announcement for its expected release
date.
