yes it is still supported. Veritas has to support the same features on any platform. that's part of the point of Veritas. go right ahead and do your experiment. while you're at it you could dig out the procedure for a more pure veritas disk.

There is no longer, with a Solaris 10 system such as your 5120, a valid reason to use VERITAS boot disk encapsulation. Use ZFS. As I recall the 5120 has hardware mirroring so you could use that or you could use ZFS mirroring. The advantage of hardware mirroring is that it doesn't come up to the OS -- but a 5120 has enough CPUs to deal with mirroring. Managing the mirror with ZFS gives you more ready access via fmadm to any disk errors rather than having them buried behind the raid controller. Use Solaris 10, preferably update 9, and ZFS for your boot. This is also very important for zones and for Live Upgrade. VERITAS has its advantages in some situations for managing data disks (for example, raw volumes and Oracle if you have an ODM license), especially older Oracle releases (all of which are certified to work on Solaris 10). LU will make ZFS snapshots and clones if you have a ZFS boot disk. If you have VERITAS-encapsulated it will first unencapsulate the boot slice. VERITAS boot encapsulation also lacks a mirrored dump device: since Vx doesn't have the API for dump, you have to give the underlying swap slice. Lose that disk lose your dump device. Vx requires swap is a slice, it's fixed in size until you manually go in and grow that slice -- if you left room on your root disk to do that operation. ZFS root, by contrast, uses a zvol for dump and a zvol for swap. They are sparse devices only using space when needed. Of course that means you can fill your entire root disk and leave nothing for dump or swap -- so you could also just create them as regular zvols with nailed-up space which you can shrink and grow manually as desired without worrying that you left room in your disk layout. boot encapsulation was the thing to do on Solaris 8 and 9. Not 10. ________________________________ From: veritas-vx-boun...@mailman.eng.auburn.edu [mailto:veritas-vx-boun...@mailman.eng.auburn.edu] On Behalf Of Asiye Yigit Sent: Wednesday, October 06, 2010 10:18 AM To: Christian Gerbrandt; veritas-vx@mailman.eng.auburn.edu Subject: Re: [Veritas-vx] couldn't encapsulate boot disk Hello; Disk is okay. I know it should be online invalid. For both T5120 systems, the problem is same. I have many disk from san and two disks internal. For the boot disk, for both system, it says error state. Disks are okay physically. There may be some point patch for SF 5.1RP2 for boot disk mirroring?
