I think the first question id 45GB restored in 5Hours, that's 5 GB hour / 1.3MBS Second... What kind of Tape Drive are you using, is it on its own HBA (Don't Mix Disk / Tape I/O down same path)
Sounds like you have an I/O challenge. As far as the Idea below, never tried, but take in consideration that if the TSM DR box is in a different geographical location you'll have to use FCIP or Disk Frame replication to gain access to those volumes. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Neil Sharp Sent: Monday, February 04, 2008 10:28 AM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] TSM DR restore query Hello I was wondering if anybody could help or advise with the following question. I need to devise a solution to speed up DR for one of my customers. Currently their DR solution is the classic restore from TSM DB tape and then load all of the off site tapes into the DR library and then perform the client restores. The problem is that the TSM DB restore can take in the region of 5 hours. The TSM DB is 45GB. I was thinking of using the following method. Can any one see any issues with this? *On the primary TSM server:* They have a Windows 2003 Standard Edition TSM server. I am proposing that we set up TSM DB and log mirroring, one copy on local disk and the second copy on SAN attached disk. *On the DR site:* They also have a TSM 2003 Standard Edition TSM server. When DR is to be tested / invoked, I would propose that they re-zone the DR TSM server to access the LUN that contains the DB and logs. Ensure that the DR TSM server's dsmserv.dsk points to the mapped drives. Note the the TSM tape library is also SAN attached. Any comments / experiences would be appreciated.
