1、3494带库问题
自6月30日,梁强佟贺更换drive1主板、drive2磁头之后,7月1日,把drive1的wwn号在交换机上配置好,之后,drive1正常使用了一天,但由于使用损坏的磁带102,造成drive1卡带,按drive1前面板的“|”重新启动drive1之后,磁带弹出来,但是drive1在系统层还是不能用,报错如下:
DAGDMCMDS01$ mtlib -l /dev/lmcp0 -m -f /dev/rmt1 -VA00490
Mount operation (errno = 5 ) Failed - Device no longer available.
drive2可以正常的抓带,在系统层可以正常的读写,但是在petrobank中下载时可以抓带,但是不能下载数据,经过与瑞飞公司朱小青和landmark公司王海东会诊之后确认为drive2设备类型发生了变化,由原来的3590h1a变为了3590e1a,造成不能识别磁带数据(3590磁带机有三种类型,B1A,E1A,H1A,H1A是最高级,E1A只能识别40GB的3590磁带,而目前使用的60GB3590磁带只能由H1A的3590drive才可以识别读写),如下信息:

IBM工程师佟贺计划下周一(7月7号)过来
之前对nettape管理软件进行重新启动,测试drive的问题,
刷新网络服务: /usr/bin/refresh -s inetd
启动nettape服务进程: /usr/lpp/nettape/bin/cltopr -S pvl -l /tmp/nettaped.log
启动nettape 3494带库服务进程:/usr/lpp/nettape/bin/cltopr -S 3494d -L dg3494 -l /tmp/nettape_3494.log
