You need the storage to be "standby" and not "reserved". Change your command to: "DEFINE STORAGE AS 700M STANDBY 300M"
As was discussed in another thread, "reserved" storage is memory that may become available (either to your virtual machine or to an LPAR) but is not currently available. "Standby" storage *is* available and can be dynamically added to your virtual machine or to an LPAR. In an LPAR, the amount of standby storage can change if other LPARs have unassigned storage added to their storage. In a virtual machine, you control the amount of standby storage vs. reserved storage with the CP command. To add it to Linux, look at the "Device Drivers" book for SLES 11: http://public.dhe.ibm.com/software/dw/linux390/docu/l26edd01.pdf 2012/4/11 Lu GL Gao <[email protected]>: > > How to dynamically increase/decrease storage for linux running on z/VM? > > Assumption: Define LPAR profile with 4G initial and 0 reserved storage. > z/VM version is 5.4 > User Direct statement for linux guest is "USER LNX1 LNX1 1G 2G > EG" > Objective: Dynamically increase/decrease guest storage. > > Before booting linux, use command"DEFINE STORAGE AS 700M RESERVED 300M" to > set 300M reserved storage for linux. > > > Question 1: If linux guest is SUSE11 or above, how to dynamically > increase/decrease storage ?? > > Question 2: If linux guest is Redhat, how to dynamically increase/decrease > storage ?? > > > > > Best Regards! > > Gao Lu (高路) > I/T Specialist > Global Technology Services > IBM Global Services (China) Company Limited. > Address:18/F, Pangu Plaza, No.27, Central North 4th Ring Road, Chaoyang > District, Beijing, 100101 > 地址：北京市朝阳区北四环中路27号盘古大观写字楼18层，100101 > BeiJing 100027, PRC > Cell Phone: 15001327619 > Internet ID: [email protected] -- Bruce Hayden z/VM and Linux on System z ATS IBM, Endicott, NY ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
