rootdisk is failing and rootmirror is out of sync

[grigori]

Hi all,

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

many thanks.

Hi,

you can use vxdiskadm menu simply to do this task ...

check out option 4 & 5

Remove a disk for replacement
Replace a failed or removed disk  

Menu based option will guide you clearly to replace your disk, while you attach the new disk, it would sync the disk with rootdisk automatically...

1- boot system into single user mode through  cdrom: boot cdrom -se
2- physically replace the disk
3- restore the root file system on the new disk
4- install the bootblock
5- edit /etc/vfstab and /etc/system and remove vx entries from both files
6- startup the system
7- encapsulate the new disk with vxdiskadm
8- attached the rootvol and swapvol volumes

thank you Gaurav,

I already did the replacement before looking at the guides you mentioned above since I was in a hurry, but I used mainly the vxvm troubleshooting guide.

thank you for replying
