Re: I5 systems in production

Here is what I had saved (for just this
occasion)...........................

===========================================

One last important note that was not brought up at COMMON's Sound Off but
has just come to our attention. There is apparently an issue with the
feature 2757 PCI-X RAID5 disk controllers, which were announced in January
2003, failing in the field. IBM has just sent out two PTFs to run as a
diagnostic tool to identify potentially faulty 2757 cards in your machine.
Those PTFs are MF33849 for OS/400 V5R2 and MF33850 for i5/OS V5R3. The
feature 2757 cards are the highest-performing RAID5 disk controllers that
IBM sells, with 235 MB of write cache memory (with data compression turned
on, this cache memory turns effectively into a 757 MB cache). It is an
Ultra3 SCSI controller that supports a RAID5 set with a minimum of three
drives, expandable to 18 drives, and up to four SCSI buses, which run at
160 MB/sec, compared with 80 MB/sec of prior cards. If you have one, get
this utility and run it now.
