Hello Christophe:
We ran into a situation yesterday, where it appears there is a limit on
the number of targets that DM Multipath can use. We are switching to a
switch/zoning configuration at our office which may present as many as
2500 targets to the system. Yesterday, we were testing a smaller config,
and the limit on the number of targets appears to be 640. When we exceed
640, the system locks up. When we try 656 targets, it locks up, then if
we back out the last 16 targets and replace them with 16 different ones,
it still locks up. We backed off the zoning for the meantime (which
cripples the connection/bandwidth) to about 280 targets, but every
filesystem multipaths properly.
Do you know what is going on, and is there some way to increase this limit?
Lance
