EVA reorg:   Reorganising the EVA into multiple disk groups with production in its own group is a really good idea. (193 words, 0 comments, 0 pings)

Recommended and supported Storage:   The storage guys at HP have just released a matrix showing the supported and recommended storage for Integrity servers. Definitely worth bookmarking. (22 words, 0 comments, 0 pings)

Confirmation of issue with SAN switch firmware:   If you've been following along, we have been experiencing fibrechannel path problems here after upgrading Brocade switch firmware. After a huge roundabout investigation by HP and Brocade, it has finally been acknowledged that the version of the SAN switch firmware we upgraded to has a problem. Of course, I guessed that back in December. (154 words, 0 comments, 0 pings)

EVA 8000 goes live:   We went live on the EVA 8000 last night. This had been delayed significantly due to our ongoing SAN issues. I have always suspected that the path issue is related to the version of firmware running on the 3200 SAN switches. As this is the minimum version required to support the EVA 8000, I was considerably worried about going live and then being told by HP that we would have to down-rev the switch firmware, leaving the EVA in an unsupported configuration. With the implementation of the 4GB switches on the weekend, if HP plays the down-rev card, I can move the EVA off the 2GBs to the 4GBs and avoid the unsupported configuration.

4GB SAN switches:   The amount of storage has once more exceeded the number of ports I had on the edge of the SAN, so today I replaced the four 2GB switches that made up the cores of the two fabrics with four 4GB switches. The 2GB switches then became new edge switches, giving us another 28 ports on the edge. (216 words, 0 comments, 0 pings)

Update on SAN issues:   The SAN issues we've been having have been narrowed down to either the HBA firmware or a problem within OpenVMS itself. (82 words, 0 comments, 0 pings)

SAN problems:   I've been a little quiet on the blog here of late as we have been struggling with a number of problems, the first of which appears to be a firmware interaction issue on our SAN. (529 words, 4 comments, 0 pings)

DLT cleaning lights:   Jim struggles with reading the SCSI specification to determine if a tape's cleaning light it on or off. (237 words, 0 comments, 0 pings)
