Hello,
i'm running in some strange problems with 2 esx server.
I have 4 lun mappings on a xyratex san with qlogic hba's.
since sunday, one special lun is running very bad performance ( ~1mb/s read/write). all other LUNs on the same storage system are fine.
the storview did not show any errors.
I already rebooted the server.
Any Ideas?
