Hello,
Hello I have XSAN with 4 MacPro's. Two of them are MDC and two clients. Suddenly the volumes disappeared from one of the clients. I checked on one of the mdc and the volumes were visible but in Xsan admin there was a message No visible luns. I turned off all computers and turned on just one of the mdc. Immediately i get a message that the system see some volumes that are not readable and offer me to initiliaze them. Xsan admin no does not see any luns and no volumes are mounted. The LUN are visible in disk utility.
OS version 10.8.5
Two RAID systems with 2 LUN's each.
Qlogic fc switch


Can you help? What is going on?
