Dear Vtrak owners!
I hope my solution will helpful for any Vtrak system and sometimes will save your nerves. In 2010 we bought very expensive configuration which is called in manual as «no single point of failure» (figure 14, page 26): E610F with two controllers, two servers, two FC switches with 2TB SATA disks (RAID 6) and AAMUXes. In 2013 we added J610SD JBOD with two controllers and 2TB disks. But e610Fd itself is single point of failure: when in 2017 we added second J610SD, created and deleted array on it (for test reason), subsystem hanged. After restart all disks except one were UNCOFIGURED, and it showed only one array with INCOMPLETE status. Promise's support said that data is gone and that I should restore backup of 50tb! Of course we cannot store 50tb of backup. Than I on my own risk accepted incomplete array, deleted it, and created it again with old parameters (order of disks, stripe size, sector size, capacity), than start server. Windows 2008 R2 saw all our files in excellent condition (chkdsk passed test with no errors)! Than I recreated with old parameters the second lost array - windows saw it too. Futhermore I tried few times to create array, copy some files on it, and then delete it and create again - files were seen again.
Support said that my solution is very specific for adding article to knowledge base, but it works. If sometimes you lose your array and see your disks as unconfigured, there is a large chance of resurrection.
