Hi,
I like to verify the steps how an dg is imported.
vxdg import dg,the vxio will issue an query on all HBA ports to find all the disks who have that dg name written on private area.right?In this query is involved vxdisk scandisk?
Also if an private area on an disk is corrupted,what is happening?The vxvm will solve it or I should to fix this issue?how?
Then the volumes are started.Now the OS is able to see the disks.right?
If an volume has metadata corrupted how I fix it?with vxrecover,vxmend or vxcfgrestore?
Also fsck?
Every volume has on it the filesystem and the data itself.right?
If I have an mirror logical volume,then at any write I/O the vxvm modules will instruct the disk driver to write in parallel the data on both partitions.right?
So when I perform mkfs -F vxvm then the disk driver will write in parallel the filesysyem on both partitions.When I use this vxassist to create an mirror,the disk driver will write in parallel on private area of both disks involved.right?
thanks.
