clone disk group
Greetings, I need to migrate disk groups between hosts. The current aging server runs vxvm 5.x on solaris 10. The proposed work loads are to be taken on by a combination of Solaris 11 and Solaris 10 logocal domains, split between application and database. I'm not using vcs only vxvm. Thevxvm version on the new platform is 7.1. Due to limitations on the storage arrays, i cannot create clones on the array and map them to the new host. Does vxvm have a cloning mechanism ? Is there is a better approach to migrate the data across different vxvm versions and maintain a point of failback. I would like to maintain the the diskgroups separately until the cutover.

How much space is required in a VxFS file system for the recover file as used by the fscdsconv utility
Hi all, I'm going to migrate a VXVM/VXFS (vers 5.1SP1RP4) volume/file system Solaris Sparc platform to VXVM/VXFS 6.03 Linux 6.5 platform, the file system size is 2TB space, real 1TB.... how much space is required for utility fscdsconv during conversion, there is a formula for this job? Thanks a lot Cecilia
Encapsulation issue on VxVM6.1
Hello, We are running Solaris X 86 and added to virtual disk and trying to mirror the root disk, but getting this error message. Continue with encapsulation? [y,n,q,?] (default: y) A new disk group rootdg will be created and the disk device c0t1d0 will be encapsulated and added to the disk group with the disk name rootdg01. VxVM ERROR V-5-2-5711 The encapsulation operation failed with the following error: VxVM vxencap ERROR V-5-2-310 The c0t1d0 disk does not appear to be prepared for this system. Hit RETURN to continue. Encapsulate other disks? [y,n,q,?] (default: n)Post 6.1 upgrade: Solaris 10 servers periodically drop and re-add physical disks
Hi, I'm seeing an interesting issue. I have a handful of Solaris 10 servers (out of about 100) that are periodically dropping a disk and adding it back into the volume manager configuration after upgrading them to Storage Foundation/Infoscale 6.1 the following sequence happens reports a disk fault,reports an issue with afailed sd & plex, reports that it is attempting to relocate the subdisk & plex, can't find a place, so thendrops the subdisk & plex, then 4 or 5 minutes later, it finds the disk and relocates the failed sd and plex on the original disk. This seems to happen every month or so for no apparent reason. The hard disks aren't having hard faults. Has anyone else experienced this behavior? Or know what can be done to make 6.1 a bit more fault tolerant to hard disk errors? Thanks, Bob
Solaris10 vx one disk failed and second is removed
Hello All, is it posible to save my data and start up from at least one good disk on a Solaris server in this case?: [root@host1:/]$ vxdisk list DEVICE TYPE DISK GROUP STATUS c1t0d0s2 auto:sliced rootdg01 rootdg online failing c1t1d0s2 auto:sliced rootdg03 rootdg online - - rootdg02 rootdg removed was:c1t1d0s2 [root@host1:/]$ I somehow started up the server from ramdisk. I'm in readonly mode, but I can manually mount FS if needed. The problem is thatc1t0d0s2 failed: WARNING: /pci@1c,600000/scsi@2 (glm0): Resetting scsi bus, got incorrect phase from (0,0) WARNING: /pci@1c,600000/scsi@2 (glm0): got SCSI bus reset WARNING: /pci@1c,600000/scsi@2 (glm0): Resetting scsi bus, got incorrect phase from (0,0) WARNING: /pci@1c,600000/scsi@2 (glm0): got SCSI bus reset WARNING: /pci@1c,600000/scsi@2/sd@0,0 (sd0): auto request sense failed (reason=reset) and the second disk c1t1d0s2 is in a strange state which I don't understand - it's part ofrootdg02 which is ok and also partofrootdg03 which is removed.I can't mount this disk c1t1d0s0,1,3,4,... [root@host1:/]$ mount /dev/dsk/c1t1d0s1 /mnt mount: I/O error mount: Cannot mount /dev/dsk/c1t1d0s1 [root@host1:/]$ Thank you for your comments.
