Replace more than one broken disks

If you want to replace more than one disk that are physically broken, you cannot read any data from these disks or write any data into these disks,

if the broken disks have been restriped they become emptied or non functional. Run the mmdeldisk command directly. Pull out the broken disks, pull in the new disks, run mmcrnsd, and then run mmadddisk to add them into the file system.

If the broken disks have not been restriped (then, it might be ready/down or ready/up), then take the following steps:

1. Disable auto recovery temporarily (refer the section 2.1, step 2)
2. Pull out the broken disks directly. You could run mmlsnsd -X to check what these pulled-out disks will be like: node7_sdn C0A80A0756FBAA89 - - gpfstest7.cn.ibm.com (not found) server node
3. Pull in the new disks.
4. mmcrnsd for the new disks (take new NSD name)
5. mmadddisk <fs-name> -F <new-nsd-file from step4>
6. To delete the broken disks from the file system, see Disk media failure.
