AIX同步鏡像VG中的新LV,手工鏡像LV 已經做鏡像的VG中,建立一個LV 如果在沒有選擇Number of COPIES of each logical partition 2 +那沒建立出為的LV 是沒有鏡像的,這時lsvg -l vgname 時新的LV就是1個PP# lsvg -l rootvgrootvg:LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINThd5 boot 1 2 2 closed/syncd N/Ahd6 paging 2 4 2 open/syncd N/Ahd8 jfs2log 1 2 2 open/syncd N/Ahd4 jfs2 2 4 2 open/syncd /hd2 jfs2 10 20 2 open/syncd /usrhd9var jfs2 3 6 2 open/syncd /varhd3 jfs2 32 64 2 open/syncd /tmphd1 jfs2 1 2 2 open/syncd /homehd10opt jfs2 2 4 2 open/syncd /opthd11admin jfs2 1 2 2 open/syncd /adminlg_dumplv sysdump 8 8 1 open/syncd N/Alivedump jfs2 1 2 2 open/syncd /var/adm/ras/livedumpfslv00 jfs2 100 100 1 open/syncd /u01 只能通過手工來進行兩塊硬碟的同步。首先查看哪塊硬碟缺少新的LV:# lspv -l hdisk0hdisk0:LV NAME LPs PPs DISTRIBUTION MOUNT POINThd8 1 1 00..00..01..00..00 N/A...livedump 1 1 00..01..00..00..00 /var/adm/ras/livedumphd11admin 1 1 00..00..01..00..00 /admin# lspv -l hdisk1hdisk1:LV NAME LPs PPs DISTRIBUTION MOUNT POINThd8 1 1 00..00..01..00..00 N/A...fslv00 100 100 00..100..00..00..00 /u01livedump 1 1 00..01..00..00..00 /var/adm/ras/livedumphd11admin 1 1 00..00..01..00..00 /admin 或者:# lslv -l fslv00fslv00:/u01PV COPIES IN BAND DISTRIBUTION hdisk1 100:000:000 100% 000:100:000:000:000 如本例,我們在hdisk0 上建立鏡像,可以通過smitty mklvcopy 或 mklvcopy fslv00 2 hdisk0 來實現,建立後查看狀態:# lsvg -l rootvgrootvg:LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINThd5 boot 1 2 2 closed/syncd N/Ahd6 paging 2 4 2 open/syncd N/A...fslv00 jfs2 100 200 2 open/stale /u01 建立成功後要用 syncvg -v rootvg 來同步,同步時間與LV大小有關,如:# nohup syncvg -v rootvg# jobs[1] + Done nohup syncvg -v rootvg & # 同步成功# lsvg -l rootvgrootvg:LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINThd5 boot 1 2 2 closed/syncd N/A...fslv00 jfs2 100 200 2 open/syncd /u01
