OnlineJFS on SUN

Lutz Wenzel — Tue, 09 Jul 2002 07:40:13 GMT

Hi all,
we are using EMC's BCVs in our backup process, i.e. mount the mirrors (OnlineJFS, HPUX 11.0) to a HPUX 11.0 backup server (OnlineJFS, HPUX 11.0, Legato Networker). Now our customer plans to replace the HPUX server by SUN hardware with Veritas Filesystem. May this work at all?

No, you can't use the Veritas File System product for Solaris for mounting Online JFS filesystens on a Sun host. In fact, even if you had purchased the Veritas file system for HPUX from veritas, you *still* wouldn't be able to do this. If your customer is determined to go with a Solaris host, he will have to do raw disk image backups of the HPUX BCVs.

Hi,

No...
Solaris doesn't support veritas.
If your customer insist on solaris then Legato storage manager is the best bet.

I agree. You can't use VxVM for Solaris for mounting Online JFS filesystem. If your customer wants to do so, you can't do a BCV-Legato Networker Backup.
Then he will have to do raw disk image backups of the HPUX BCVs. In thise case another Backup tool e.g. LGTO Storage Manager or LGTO Celestra woulb be a good idea.

Celestra Power moves data at a block level - directly from disk to tape. Data travels at high-speed using a Celestra copy command that resides on a separate server, freeing application servers from the strain of backup processing. Storage assets are protected, application performance remains good.

So tell your customer to think twice.

Your customer is going to be very disappointed with the IO throughput of a SUN box. I haven't found a SUN box that behaves well under heavy IO conditions, even with their new Sun Blade 2000.

Generally, mounting disks directly from one operating system onto system running a different operating system (HPUX/Solaris/ATX, etc) is not supported.

However, you could get away with NFS mounting the disks.

P.S. Replacing both systems with Sun systems will work.

Hi

Sun is poor in vloume maangement , there are some tools like disktools etc which are helpful and have some GUI to help you but overall the volume mgmt in SUN is poor ,you should revaluate the whole decision .
