我真是菜鸟。屋漏偏遇连天雨。刚接手备份这块儿任务,还没摸明白,就碰到数个难题。我现在的带库是IBM3582, media server或备份服务器是windows 2003, clients 基本上都是solaris 9 的SUN server. 单位加了一个date domain 来加强备份能力。设置了两台client 作为storage node。结果发现,只要这两台storage node重起,就会发现这两个服务器上的光纤设备顺序总会发生变化,是的备份无法进行。目前只好在备份服务器上legato 控制台上重新配置设备。很烦,很烦。据说可以将这些设备的顺序固定下来。可是我不知道该怎么做。只好在这里请教各位高手了。\r\n比如,目前在/dev/rmt下可以看到的设备顺序是下面的一种情况。\r\n\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 12m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@2,0:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 13m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,0:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 15m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,1:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 16m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,2:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 17m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,3:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 18m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,4:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 19m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,5:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 20m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,6:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 21m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,7:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 22m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@4,0:m\r\n\r\n当重起以后,有可能变成:\r\n\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 12m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@2,0:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 13m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@4,0:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 15m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,1:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 16m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,2:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 17m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,3:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 18m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,4:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 19m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,5:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 20m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,6:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 21m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,7:m\r\nlrwxrwxrwx 1 root other 50 May 6 10:09 22m -> ../../devices/pci@1\r\nf,2000/fibre-channel@1/st@3,0:m |
