Badly need your help,i have this issue in /etc/lvmtab. We have EMC Symmetrix storage on our system. The case is one of the volume in one of our server experience a disk error ( BCV disk ) so i have to re-map a reserve disk to take the place of the defective disk. This defective this happens to be a BCV disk which we usually use for full DB synchronization for us to create a DB replica. So i re-mapped a new disk then proceeded with the disk sync but upon activating the VG using the new set of disks i keep on encountering this error "unable to locate address /dev/rdsk/c0t4d5 in /etc/lvmtab". Does anyone can help me with this.
FYI! I have done the same procedure twice in remapping the BCV disk but i'd never encounter such error as this....
thank's & kind regards,
John

Check this disk is belongs to which volume group. Seems your need to do a vgextend to include this disk in the vg , or do a # vgscan -p -v -a , and check if the disk gets located ,
You will need to re-import the vg - vgexport it, then vgimport -p -s -m /tmp/yourvg.map /dev/vgXX (don't forget to mkdir /dev/vgXX and mknod the group file first)...
- Create a new VG dir and group file eg. # mkdir /dev/vg02 # mknod group c 64 0x020000 - vgimport your lun's # vgimport vg02 <your_lun_device> - vgchange your VG to active # vgchange -a y vg02 - Mount your filesystems...
Voila...
Check your /etc/lvmtab file by doing an additional # strings /etc/lvmtab To see if your lvmtab looks ok.
If your lvol names are nonstandard (i.e. NOT lvol1, lvol2, lvolx etc...). You might need to create a 'map' file to make sure the lvol names are to your liking. You should be able to create a mapfile from any VG then change it to reflect your situation. Be VERY careful with this though.
