APAR status

  • Closed as program error.

Error description

  • The last files of a restore of a lanfree client are listed as
"unavailable" by TSM, when using UFS on Solaris for TSM lanfree
volumes.  The issue shows up on TSM restore because TSM opens
the file read/write, which the UFS MDC was misinterpreting as
meaning the file was being created.  Therefore the MDC was
truncating the file back to 0 and corrupting the TSM backup
volume.

Local fix

  • none - upgrade sanergy mdc to 3.3.6.9 or later for fix.

Problem summary

  • The Solaris UFS MDC was truncating files that w
ere open for write inappropriately. TSM opens the last volume du
ring a restore as read-write and the SANergy MDC took the read-w
rite to mean truncate the file to 0 and set the size tothe first
 hyper extension. The effect of the trncation is that TSM report
s back data unavailable during the restore. This is fixed in SAN
ergy v3.3.6.9 and later.

Problem conclusion

  • 



Temporary fix
