rootdisk is failing and rootmirror is out of sync
I have encapsulated my rootdisk and rootmirror under vxvm long time ago, now the root disk is shown as failing when I execute "vxdisk list" and also I discovered that after my last reboot 3 weeks ago , the rootvol-02 (rootmirror disk) is out of sync, so my system is running on rootvol having only one stripe available, the other stripe is out of sync.
I have alrady purchased a replacement for my root disk, my question is how to replace the disk knowing that it is encapsulated under VxVM.
I have the headlines in my mind but I am not sure about the commands. can someone help me please?
my environment contains the following boxes:
1- Solaris 10 + SF 5.0
2- EMC CX120 array + multipathing
3- old ufs backup using ufsdump is available for the root file system
