My company have encountered similar problems, and we have seen that some settings need to be set.
Here are the settings which have to be implemented.
Each child fibre device (fscsiX) has to have the following two modes set:
Code:
chdev -l fscsiX -a dyntrk=yes -a fc_err_recov=fast_fail
Additionally, every hdisk device needs to be changed (which I didn't see mentioned in the post).
Code:
chdev -l hdiskX -a reserve_policy=no_reserve
Lastly, you may want to check that the hcheck_interval is NOT set to 0, as then it won't check at all. Usual recommendation is to set to 30 (but 10 should be sufficient).
Code:
chdev -l hdiskX -a hcheck_interval=10

On a particular LPAR, I was running AIX 5.3 TL 3. On Monday I did an update of the LPAR to 5.3 TL 9 SP2. The install was smooth, but then I ran into a problem.
The MPIO driver does not work with LSI's StoreAge (SVM4). I did some looking, and looks like

Dear Solaris Experts,
We are upgrading from sun4u to T4 systems and one proposal is to use LDOMs and also zones within LDOMs.
Someone advised using only zones and not LDOMs because the new machines have fewer chips and if a chip or a core fails then it doesn't impact the zones, but impacts... (3 Replies)
