BR0252E while taking sap offline backup on disk

[Former Member]

Hi ,

I have just added up an additional disk to take sap offline/online backup on this disk , made changes accrodingly in init<sid>.sap as device type and also the path of the backup directory. Having also given the permission according to the file system i.e. /backup from "saproot.sh" , but still I'm getting error as

BR0252E Function mkdir() failed for '/backup/ank/bebobqxm' at location BrDirCreate-1

BR0253E errno 30: Read-only file system

Does anybody has come across this type of error, Pl let me know.

Thanks & Best Regards,

Aparna

Hi, as you can read you have mounted Read-only file system , try to read on your OS forums how you need mount this file system not in Read-only

Hi,

Just a hunch - but worth checking all the same:

1) You say you have run saproot.sh, so ownership of brbackup should now be 'orad50' instead of 'd50adm', and the Set UID bit is switched on. Please doublecheck this.

2) Also check that the file system containing the SAP kernel (/sapmnt/D50) has not been mounted with the 'nosuid' option. I have known over-zealous UNIX administrators to do this without asking.

The information you send seems consistent with the backup running with the 'd50adm' identity instead of 'orad50'.
