Debian iSCSI mounts as RO. How to make RW?

Question

linux

Hello Lord!
Somewhere I'm dumb. Lead to the true path.
Is available QSAN with a heap of disks, are collected in RAID 5 (20 TB volume). Some data is already there. QSAN can only distribute iSCSI.
Task: to attach it to the Debian server, so that the latter distributes data wisely.
What has already happened: iSCSI was detected from the Debian server. The system has an additional disk device /dev/sdd and with it another /dev/sdd1 and /dev/sdd2. On sdd2, in fact, the data lives.
Then everything is simple... mount /dev/sdd2 /mnt/ISCSI
Everything mounted perfectly. The necessary data lives in /mnt/ISCSI. It seems like everything is fucked up. But no! This data is read only! And I can't figure out how to make them RW.
I connect the view with iSCSI - everything is fine. RW. And in Linux only read only.
How to make RW in Linux?
PS Of course, mount -w /dev/sdd2 /mnt/ISCSI didn't give the desired result.

Actually, the issue was resolved, but somehow clumsily.
It was mount that did not want to mount iscsi in RW.
I'll expand on the "basic" information a bit.
The fact is that iscsi already had data. Those. the drive (block device) has been formatted to NTFS and is full.
It turns out that for some reason, for me, it was not clear yet, it was with NTFS that the plugging happened. Either the volume of the "disk" is too large, or the stars did not converge so well, but the Read Only device was mounted.
I rummaged through the ntfs repository and... I found what the hell: ntfs-utils. Posted for informational purposes. This package pulled an insane amount of additional packages for graphics, which I never need on the server. Already going to demolish, but decided to try to mount the device again. Ops! Happened! Now in RW mode!
For a complete buzz, I would like to understand why this problem was and how ntfs-utils helped in solving it? More precisely, what is it that ntfs-utils allowed to mount in RW? I really want to remove this ntfs-utils with all the garbage that it pulled with it.
