Troubleshooting Questions and Answers
Chapter 12 Solving Problems 139
Why am I prompted for a user name and password when I add an iSCSI
Storage Host to a Management Service?
One reason you may be prompted for a user name and password is if the iSCSI
Storage Host you are adding was added to another Management Service
previously. Enter the Windows user name and Administrative password for that
iSCSI Storage Host.
Why are some of my pools greyed-out in Adaptec Storage Manager?
• If you have transferred a disk drive that was used for direct attached storage to
your iSCSI Storage Appliance, any arrays that were stored on that disk drive will
appear as alien pools .
In Adaptec Storage Manager, alien pools are greyed-out in the Logical Devices
View and can’t be used to store data. Delete these alien pools from Adaptec
Storage Manager. See “Deleting an Individual Pool” on page 94 or “Deleting All
Pools” on page 95 for instructions.
• If you update your iSCSI Storage Appliance to a new image of the operating
system (see page 105), then delete a pool, that pool will appear offline if you then
revert to the previous image of the operating system. You can’t delete an offline
pool from Adaptec Storage Manager.
Why did my volume creation/reassign job fail or seem to fail?
Currently, volume creation jobs may fail or appear to fail if they are started during a
period of heavy I/O activity while your iSCSI Storage Appliance is also in the
process of creating or rebuilding a pool. To resolve the problem, wait to create a
volume until pool creation is complete or I/O activity has decreased.
A volume creation or reassign job will fail if its selected mount point is already in
use.
Why can’t I connect to a newly imported pool?
If authentication is set on a pool which is exported from one iSCSI Storage
Appliance and imported to another, you must reset authentication on the pool once
it’s imported.Why did my recurring snapshot job fail?
If you set up a recurring job that creates and mounts a snapshot on the same disk
drive, you must free the disk drive after each job or the job will fail.
