具体步骤可以参考红皮书《DS4000 Best Practices and Performance Tuning Guide》SG24-6363-03。\r\n章节11.1.8 DS4000 series – dynamic functions。里面有step by step步骤。\r\n摘录简要说明如下：\r\nFor Dynamic Volume Expansion:\r\n- DVE support for AIX requires AIX 5.2 or later.\r\n= DVE for AIX 5.3 requires PTF U499974 installed before expanding any file systems.\r\nIn reality, in AIX there is no real Dynamic Volume Expansion because after increasing the\r\nsize of the logical drive under the DS4000 Storage Manager, it is necessary, to use the\r\nadditional disk space, to modify the volume group which contains that drive. A little downtime\r\nis required to perform the operation that is: stop the application, unmount all filesystems on\r\nthis volume group and then varyoff the vg. At this point you need to change the characteristics\r\nof the volume group with chvg -g vgname, varyon the volume group, mount filesystems, and\r\nrestart the application.\r\n\r\n注意要求的AIX补丁。并做好备份。
