I've used Hitachi USP and 9980 DASD with our AIX 6.1 boxes. It was in a Raid 5 configuration so we didn't do any mirroring on our side. It worked well and was very fast. If you are using on a server with physical fiber cards assigned to it, like a VIO server, you need to install the HTC_MPIO_ODM_5400I and HTC_MPIO_ODM_5401U filesets so that AIX correctly recognizes the disks. Without those, the "lscfg" AIX command will call them something like "FCSCI Other". With it, the output looks like this:
Before you add too many disks, you will want to set these fiber card attributes:
With every LUN (hdisk) we were assigned, we set the following disk attributes on our VIO servers:
Since, the disk changes cannot be made "on-the-fly", I set the attributes with the "-P" and then did "rmdev -l hdisk5" followed by "mkdev -l hdisk5". This took the disk out of the system configuration and then brought it back in with the attributes set appropriately.
We always had good luck with Hitachi USP and 9980 disks.

hi,
i'm new to this company and i'm using old AIX 4.3 with DAS and SSA storage. What is the best way to query a report for disk capacity, usage, free, etc.
I know in AIX 5 there's a command for "du -g /" or "du -m /" to report the total usage but I'm not using AIX5. In AIX 4.3 I can use "df... (5 Replies)
