sclp_cmd.4336b4 Standby memory at 0x<start address of standby memory> (<usable memory in MB> of <total detected memory in MB> usable)

Explanation

Standby memory was detected. It can be used for memory hotplug only if it is aligned to the Linux hotplug memory block size. If the aligned amount of memory matches the total amount, all detected standby memory can be used. Otherwise, some of the detected memory is unaligned and cannot be used.

User response

None, if the usable and the total amount of detected standby memory match. If the amounts of memory do not match, check the memory setup of your guest virtual machine and ensure that the standby memory start and end address is aligned to the Linux hotplug memory block size. On Linux, issue "cat /sys/devices/system/memory/block_size_bytes" to find the hotplug memory block size value in hexadecimal notation. On z/VM, query your memory setup with "vmcp q v store".
