Recovery from the primary failure
To recover from a failure at the primary site, you will need to do the following steps at the secondary
DR550.
For Single Node implementation (Assuming the AIX server within the secondary DR550 is
operational):
Remember that the remote server is not configured to bring up the SSAM server
automatically at boot time. If it does start automatically, then disable auto start of the SSAM
server using the following commands (execute ‘‘rmitab autoserv’’ command at AIX prompt as root
id.) and disable varyon volume groups. (execute ‘‘chvg ---a’n’ <volume groupname> - for all volume
groups except rootvg). --- this is still true for operational AIX just like one below….not to have
TSM up and VGs are down.
1. From the integrated consoles, logon to AIX using the DR550 userid
2. Switch to Root and enter the appropriate password
3. From Root, execute ‘‘cfgmgr’’
4. Enter the following commands
o varyonvg ---y TSMApps, hdisk2
o varyonvg ---y TSMDbLogs, hdisk3
o varyonvg ---y TSMDbBkup, hdisk4
o varyonvg ---y TSMStg hdisk5
5. Then issue the following mount commands
o mount /tsm,
o mount /tsmDb,
o mount /tsmLog,
o mount /tsmdbbkup
6. Change directories using the following command: cd /usr/tivoli/tsm/server/bin
7. Issue the following command: nohup rc.adsmserv &
