第2题：

The system administrator notices that there is an I/O bottleneck on one of three disks in datavg volume group. This problem disk contains the JFS log， loglv00 and one filesystem， /mydatabase.  There are no other logical volumes on this disk.  Which of the following options would be the best solution？（）

  • A、 Increase the size of the JFS log logical volume so more transacations can be written to this log.
  • B、 Create a second， additional JFS log and have the /mydatabase logical volume point to both JFS logs.
  • C、 Migrate the JFS log device to another physical disk in the same volume group.
  • D、 Only one JFS log device for each volume group can be used.  Use the migratepv command to move the JFS log device to an empty disk in another volume group.

A client partition has the rootvg disks mapped from two separate VIO servers. They are using AIX mirroring to provide redundancy on rootvg. One of the VIO servers was taken down for maintenance and is now back on-line. The client partitions now show Physical Partition Marked Stale in the errpt. Which of the following will most likely resolve the problem？（）

  • A、Run cfgmgr to re-scan the devices.
  • B、Run mkvdev on the VIO server to re-create the devices and re-mirror rootvg.
  • C、Run varyonvg rootvg to refresh the volume group.
  • D、Run syncvg on the rootvg to synchronize rootvg.
