Hi, I have a question here on z/VM minidisk cache. By default, z/VM minidisk cache is enable. As I know, z/VM minidisk cache is using z/VM real memory and expanded storage. Would anyone recommend to use minidisk cache on z/VM where the main purpose of z/VM here is to support Linux guests? To

qeth utilities [equivalent rarp]?

2006-03-31 Thread Johnny Tan
Hi All, I would like to ask about the qeth utilities. As far as I know, Linux on Mainframe is not able to display the MAC address of the servers in the same network / subnet using arp. Hence, the equivalent "arp" program for Linux on Mainframe will be "qetharp". Is there any equivalent "rarp"
