Extending a protected file system beyond the limit of the region (block) size - assure_mimix - 6.0

To extend a protected file system beyond the max file system size supported by the region size in blocks, the logical volume region size must be increased. See the Region Size (blocks) column in the table above.

1. On the production server, stop applications that are using the Assure MIMIX for AIX protected logical volumes.

2. On the recovery server, stop applications that are using logical volumes from an active snapshot.

3. On the production server, use rtstop to unmount protected file systems, transfer any current LFC data to the recovery server and unload the Assure MIMIX for AIX Production Server Drivers.

   /usr/scrt/bin/rtstop -FSC <Context ID>

   Note:  If you cannot unmount file systems, specify the fuser -c command to locate the processes that are holding the file system(s) open.

4. On the recovery server, use rtstop to unmount any snapshot file systems and unload the Assure MIMIX for AIX recovery server drivers.

   /usr/scrt/bin/rtstop -FC <Context ID>

   Note:  If you cannot unmount file systems, specify the fuser -c command to locate the processes that are holding the file system(s) open.

5. On the production and recovery servers, use rtattr to change the region size. See the Region Size (blocks) column in the table above.

   rtattr -C <Context ID> -o smf_<LV> -a Size -v <new size>

6. On the production and recovery servers, use scsetup to delete device special files from /dev.

   scsetup -XC <Context ID>

7. On the production and recovery servers, use scsetup to remove configured Assure MIMIX for AIX LV's:

   scsetup -RC <Context ID>

8. On the production and recovery servers, use sccfgd_delcfg to delete the Failover Context ID if one was configured.

   sccfgd_delcfg <Failover Context ID>

9. On the production and recovery servers, use scsetup to create new configured logical volumes.

   scsetup -MC <Context ID>

10. On the production and recovery servers, use rtdr to create a failover context if one was configured.

    rtdr -C <Primary Context ID> -F <Failover Context ID> setup

11. On the production server, use scconfig to wipe the state maps clean (0.000% dirty).

    scconfig -WC <Context ID>

12. On the Production and Recovery Servers, use rtstart to start Assure MIMIX for AIX.

    rtstart -C <Context ID>

13. On the production server, use “smit chfs” command to extend the file system.
