我在进行AIX系统备份时操作如下:
#tctl -f /dev/rmt0 rewind
#smit mksysb
在"备份设备或文件"中添入"/dev/rmt0"后回车.
执行结果如下:
COMMAND STATUS
Command: OK stdout: yes stderr: no
Before command completion, additional instructions may appear below.

请问:
1、我备份的系统有多大?
2、bosboot: Boot image is 25562 512 byte blocks.这个boot image 的大小是多少,如何看?
3、里面提示的attention部分是指备份boot image失败,不能用吗?还有就是提到的system limit值是多少呢? |
